Initial implementation of Excel's tables feature (i.e. Select Home >
Format as Table in Excel App).
Tables are similar to AutoFilter but tables have other advantages like
named ranges, easy formatting, totals row and header row with filter.
Tables can also be converted to charts and pivot tables easily.
Usage:
$table = new Table();
$table->setName('Sales_Data');
$table->setRange('A1:D17');
$spreadsheet->getActiveSheet()->addTable($table);
In this Commit:
- Added Table API with initial support for header and totals row.
- Added complete styling options for Table.
- Added Xlsx Writer for Table.
- Added samples.
- Covered with unit tests.
To be done:
- Filter expressions similar to AutoFilter.
- Precalucate formulas for totals row (Check sample 2).
- Table named ranges in formulas and calculation.
Sample39 was not adjusted when Defined Name support was changed to include both relative and absolute addresses. As a result, the Xlsx output is currently incorrect. The Xls output is in even worse shape, since PhpSpreadsheet 'Cannot yet write formulae with defined names to Xls' (see Writer/Xls/Parser.php). (Working around that restriction was the reason for my first contribution to this project.) The sample is changed to define its named ranges properly, and to produce only Xlsx output.
* Fixed handling of inline strings
* Added an example for the "inline string" datatype for which the generated XML was fixed in the previous commit.
* Handle inline strings exactly the same way as regular strings in the XLS writer, because this is only relevant in the XLSX format.
* Allow single-cell checks on conditional styles, even when the style is configured for a range of cells
* Work on the CellMatcher logic to evaluate Conditionals for a cell based on its value, and identify which conditional styles should be applied
* Refactor style merging and cell matching for conditional formatting into separate classes; this should make it easier to test, and easier to extend for other CF expressions subsequently
* Added support for containsErrors and notContainsErrors
* Initial work on a wizard to help simplify created Conditional Formatting rules, to ensure that the correct expressions are set
* Further work on extending the Conditional Formatting rules to cover more of the options that are available in MS Excel
* Prevent phpcs-fixer from removing class @method annotations, used to identify the signature for magic methods used in Wizard classes
* Implement `fromConditional()`` method to allow the creation of a CF Wizard from an existing Conditional
* Ensure that xlsx Reader picks up the timePeriod attribute for DatesOccurring CF Rules
* Allow Duplicates/Uniques CF Rules to be recognised in the Xlsx Reader
* Basic Xlsx reading of CF Rules/Styles from <extLst><ext><ConditinalFormattings> element, and not just the <ConditinalFormatting> element of the worksheet
* Add some validation for operands passed to the CF Wizards
- remove any leading ``=` from formulae, because they'll be embedded into other formulae
- unwrap any string literals from quotes, because that's also handled internally
Handle cross-worksheet cell references in cellReferences and Formulae/Expressions
* re-baseline phpstan
* Update Change Log with details of the CF Improvements
* Fill Pattern Start and End Colors
Fix#2441. The Fill constructor sets start color to white and end color to black and the Xlsx writer writes these values to the output file. This appears to be the wrong setting for all 7 LIGHT* pattern types, 2 of the 7 DARK* patterns (DARKGRAY and DARKTRELLIS), and 1 of the 3 GRAY patterns (GRAY0625). When the wrong colors are written at save time, those patterns are not as expected. Xls writer does not appear to have the same problem.
The XML does not require either a start or end color, and the omission of these colors in the file being read was responsible for the problem. The code is changed to mimic that behavior by omitting the color tags at write time if they have not changed from when they were created by the Fill constructor (they will be written for gradient or solid patterns regardless).
This is another change which is easier to confirm via samples rather than tests. There are separate samples for Xlsx and Xls; as Excel will be quick to warn you, Xls is not as fully functional as Xlsx with respect to fill patterns. The samples do include a cell where one of the cells (LightGrid in C11) explicitly specifies the "default" colors.
* Scrutinizer
It somehow ascribed to me a problem in code which was unchanged by this PR. Correct it anyhow, along with some Phpstan fixes (errors now ignored because of change).
* Added Tests
Also corrected some docBlock problems with Style/*/parent and getSharedComponent.
* Create 2 Abstract Methods
Scrutinizer complained that 2 methods found in all Supervisor sub-types were not defined in Supervisor. Add abstract methods to satisfy it.
* Scrutinizer Ignoring Typehints
Try this instead.
* Slight Improvement
Better handling of Style->getParent().
* Name Clashes Between Parsed and Unparsed Drawings
This is at least a partial fix for #2396 and #1767 (which has been around for a long time). PhpSpreadsheet renames drawing XML files when it reads them from a spreadsheet. However, when it writes unparsed drawing files, it uses the original names, which can result in a clash with the renamed files. The solution in this PR is to write the unparsed files using the same renaming convention as the the others.
This is an incredibly simple fix, basically a one-line change, for such a long-lived problem. It is conceivable that this PR breaks a more sophisticated file than I have come across, e.g. with multiple unparsed files associated with a single worksheet. However, this PR does fix at least part of the problem for both issues, and causes no regression issues. The changed code was covered in only 2 tests - Reader/XlsxTest testLoadSaveWithEmptyDrawings and Writer/Xlsx/UnparsedDataTest testLoadSaveXlsxWithUnparsedData.
2396 is covered by a new test Unparsed2396Test. I had trouble figuring out what to test for 1767. Since it is a problem that becomes evident only when the output file is opened in Excel, I added a new sample to cover it.
* Sloppy Errors
I neglected to run php-cs-fixer and phpstan, and it bit me.
* Scrutinizer
It's not as good as Phpstan at recognizing problems that can't happen due to previous assertions.
* Scrutinizer Again
It can be really stupid sometimes.
Fix#2432. Probably for memory reasons, PhpSpreadsheet divides its data into chunks when writing to Mpdf. However, if the first chunk has so many styles that the `body` tag is not included in the chunk, Mpdf will not handle it correctly. Code is changed to ensure that the first chunk always contains the body tag.
Because this error becomes evident only when opening the PDF file itself, it is difficult to write a test case. I have instead added a new sample file which meets the conditions which would have led to the error, and which can be examined to show that it is created correctly.
* Special Characters in Image File Name
Fix#2415. Fix#1470. If path name of image contains anything other than ASCII, or if it contains # or space or probably other exceptions, PhpSpreadsheet creates a file that Excel cannot, for whatever reason, read (it is valid xml). When adding an image to a spreadsheet, Excel does not retain the original path name; PhpSpreadsheet does, but probably shouldn't. It is changed to save the image file in the zip as the MD5 hash of the original path name. This produces a file that Excel can read. In addition, it ensures that, if the image is used in multiple places, it is saved in the Excel file only once.
Because this error becomes evident only when opening the file in Excel, it is difficult to write a test case. I have instead duplicated sample Basic/05... using image files whose names match the reported error conditions.
* Scrutinizer Minor Error
Remove some newly dead code.
* Tweaks to Input File Validation
This started as a response to issue #1718, for which it is a partial (not complete) solution. The following changes are made:
- canRead can currently throw an exception. This seems wrong. It should just return true/false.
- Breaking change of sorts. When AssertFile encounters a non-existent or unreadable file, it throws InvalidArgumentException. This does not make sense. I have changed it to throw PhpSpreadsheet/Reader/Exception.
- Since the previous bullet item required changing of most of the Reader files anyhow, this is a good time to add explicit typing for canRead in the function signature rather than the DocBlock. Since all the canRead functions inherit from an abstract version in IReader, they all have to be changed simulatneously. Except for Xlsx and Ods, most of the Reader files are otherwise unchanged.
- AssertFile is changed to add an optional "zip member" parameter. It will check for the existence of an appropriate member in what is supposed to be a zip file. It is used by Xlsx and Ods.
- Verifying that a given file is a valid zip ought to be a feature of ZipArchive. Thanks to a particularly nasty bug in php/libzip (see https://bugs.php.net/bug.php?id=81222), it is unsafe to attempt to open a zero-length file as a zip archive. There is a solution, but it does not apply to all the PHP releases which we support, and isn't even necessarily supported on all the point versions of the PHP versions which we do support. I have coded up a manual test for "valid zip", with a comment pointing to the spec.
- In theory, tests now cover 100% of the code in Shared/File. In practice ... One of the tests require that chmod works properly, which is not quite true on Windows systems, so that test is skipped on Windows. Another test requires that php.ini uses a non-default value for upload_temp_dir (can't be overridden in application code), which is probably not the case when Github runs the unit tests, so that test is skipped when appropriate. I have run tests for both on systems where they are not skipped.
* Update File.php
* Scrutinizer Timeout
It's not actually timing out, it's just waiting for something to finish that finished ages ago. Making a meaningless comment change in hopes that will clear the jam. Not particularly hopeful.
Most of the remaining 32-bit-unsafe date handling that remains in PhpSpreadsheet is in AutoFilter. Cleaning this up demonstrated that there are a lot of problems with AutoFilter, and I will do it in two pieces. Part 1 was PR #2141 which I have just merged.
In this PR:
- Fix remaining 32-bit dates in filterTestInDateGroupSet.
- Also in some of the existing AutoFilter samples. Note that the comments in two of those said the filter was being set for the first day of each month, but the code specifies the last day - I have corrected the comments.
- Remove mocking in unit tests for AutoFilter in favor of 'real' tests.
- Code coverage is now 100% in all of AutoFilter, AutoFilter/Column, and AutoFilter/Common/Rule.
- No remaining AutoFilter(/Column(/Rule)) exceptions in Phpstan baseline.
- Documentation for escaping of asterisk, question mark, and tilde in text filters included spurious backslashes which are now removed.
- Text filter escaping of question mark did not work. There had been no unit tests for any text filtering.
- Likewise there had been no testing for TopTen.
- Above- and below- average filters were not working because they acquired their Calculation instance incorrectly. There had been no tests.
- Several unchanging private static arrays in Rule were changed to private const arrays.
- Clones are now tested.
- RuleTest is moved to same directory as other tests.
Specifically, the default for these two functions has been changed from `ENT_COMPAT` to `ENT_QUOTES | ENT_SUBSTITUTE`
This PR configures the argument used for those functions in Settings, and then explicitly applies it everywhere they are used in the codebase.
Most of the remaining 32-bit-unsafe date handling that remains in PhpSpreadsheet is in AutoFilter. Cleaning this up demonstrated that there are a lot of problems with AutoFilter, and I will do it in (probably two) pieces.
In this PR:
- Dynamic date processing was really wrong. There were no tests nor samples to exercise this code. (If you need details, you can try running the new sample against old code.) It is completely re-written.
- ThisYear/Month/Week/Quarter had been omitted.
- Rules such as AUTOFILTER_RULETYPE_DYNAMIC_MONTH_2 were almost correct, but showed some off-by-1 errors. I suspect these were timezone-related, and therefore more obvious to those of us far away from Greenwich.
- All Autofilter tests are moved to a single directory.
- The documentation suggested using null with the Dynamic Date setup, but Phpstan did not like that in my new tests/samples. Rather than change the doc block, I changed the documentation to suggest null string.
- I created a new sample to generate sheets using all the dynamic filters.
- I have added some new unit tests for each of the dynamic filters. I would love to be able to add some "time travel" tests because the dynamic nature of the filter makes most of the results change from day to day, which presents significant challenges in writing comprehensive unit tests (the same is true for code coverage). I was not able to find a good way to simulate time within PhpUnit, but the Linux 'faketime' package was extraordinarily easy and helpful in allowing me to confirm some edge cases. I had less satisfactory results with some Windows equivalents, but was still able to run some tests.
- Code coverage increases from below 60% to above 80%.
To be done:
- Some 32-bit unsafe dates remain in filterTestInDateGroupSet.
- Also in some of the existing AutoFilter samples.
- Study existing unit tests for AutoFilter which use mocking to see if they can/should be replaced with 'real' tests.
- Improve code coverage in AutoFilter, AutoFilter/Column, and AutoFilter/Common/Rule.
* Document Properties - Coverage and 32-bit-safe Timestamps
While researching an issue, I noticed that coverage of Document/Properties was poor. Further, the use of int timestamps will eventually lead to problems for 32-bit PHP (see issue #1826).
Coverage Changes:
- Many property types with no special handling are enumerated but not tested. These are removed, but will continue to function as before.
- Existing code theoretically allows property to be set to an object, but there is no means to read or write such a property, and, even if there were, I don't believe Excel supports it. Setting a property to an object will now be changed to a no-op (can throw an exception if preferred).
- Since the Properties object now has no members which are themselves objects, there is no need for a deep clone. The untested __clone method is removed.
- Large switch statements are replaced with associative arrays. Scrutinizer will like that.
- Coverage is now 100%.
<!-- end of coverage changes list -->
Timestamp Changes:
- Timestamps will be stored as int if possible, or float if not. This is, or will soon be, needed for 32-bit systems. Tests have been added for beyond-epoch dates, and run successfully with 32-bit.
- LibreOffice doesn't quite get the Created/Modified properties correct. These are written to the file as a string which includes offset from UTC, but LibreOffice ignores the offset portion when displaying them. Code had been generating these in UTC, but now generates them in default timezone, which should meet user's expectations.
<!-- end of timestamp changes list -->
Other Changes:
- Custom properties added to ODS Writer.
- Samples had not been generating any ODS files. One is now generated.
- Ods uses a single 'keywords' property rather than multiple 'keyword' properties.
- Breaking change - default company is changed to null string from Microsoft Corporation.
- Breaking change of sorts - PropertiesTest incorrectly tested a custom date property against a string, Reader/XlsxTest correctly tested against a timestamp converted to a string. PropertiesTest was defective, and will no longer work as coded; anyone using it as a model will likewise have a problem.
- PHP8.1 has been complaining for weeks about a time zone conversion test. I have now downloaded a version, and changed the code so that it will work in 8.1 as well as prior releases. (It is still likely that the existing code should work in 8.1, but I haven't yet figured out how to file a bug report.) In the course of testing, 3 additional 8.1 problems were reported (all along the lines of "can't pass null to strpos"), and are fixed with null coercion.
- Two Calculation tests failed because of large results on 32-bit system. These are corrected by allowing the functions involved to return float|int rather than int. I suspect that there are other functions with this problem, and will investigate as a follow-up activity.
- See issue #2090. I believe that changes between 17.1 and master will merely cause the problematic spreadsheet to fail in a different way. I believe that enclosing in quotes some variables passed to Document/Properties by Reader/Xlsx will eliminate the problem, but, in the absence of an example file, cannot say for sure.
- Properties tests are now separated out from Reader/XlsxTest and Reader/OdsTest, and now test both Read and Write (via reload).
<!-- end of other changes list -->
Miscellaneous Notes:
- There remains no support for Custom Properties in Xls Reader or Writer.
- We now have default timezones for all of PHP itself, Shared/Date, and Shared/Timezone. That is least one too many. I was unable to disentangle the latter two for this change, but will look into deprecating one or the other in future.

19_NamedRange.php was not changed to use absolute addressing when that was introduced to Named Ranges. Consequently, the output from this sample has been wrong ever since, for both Xls and Xlsx.
There was an additional problem with Xls. It appears that the Xls Writer Parser does not parse multiple concatenations using the ampersand operator correctly. So, `=B1+" "+B2` was parsed as `=B1+" "`. I believe that this is due to ampersand being treated as a condition rather than an operator; `A1>A2>A3` isn't valid, but `A1&A2&A3` is. My original PR (#1992, which I will now close) only partially resolved this, but I think moving ampersand handling from `condition` to `expression` is fully successful.
There are already more than ample tests for Named Ranges, so I did not add a new one for that purpose. However, I did add a new test for the Xls parser problem.
As issue #2042 documents, SUM behaves differently with invalid strings depending on whether they come from a cell or are used as literals in the formula. SUM is not alone in this regard; COUNTA is another function within this behavior, and the solution to this one is modeled on COUNTA. New tests are added for SUM, and the resulting tests are duplicated to confirm correct behavior for both cells and literals.
Samples 16 (CSV), 17 (Html), and 21 (PDF) were adversely affected by this problem. 17 and 21 were immediately fixed, but 16 had another problem - Excel was not interpreting the UTF8 currency symbols correctly, even though the file was saved with a BOM. After some experimenting, it appears that the `sep=;` line generated by setExcelCompatibility(true) causes Excel to mis-handle the file. This seems like a bug - there is apparently no way to save a UTF-8 CSV with non-ASCII characters which specifies a non-standard separator which Excel will open correctly. I don't know if this is a recent change or if it is just the case that nobody noticed this problem till now. So, I changed Sample 16 to use setUseBom rather than setExcelCompatibility, which solved its problem. I then added new tests for setExcelCompatibility, with documentation of this problem.

* Stacked Alignment - Use Class Constant Rather than Literal
PR #1580 defined constants for "stacked" alignment in cells.
Using those constants outside of Style/Alignment was beyond the
scope of the original PR, but I said I would get to it.
This PR replaces all uses of literal -165, and appropriate uses of
literal 255, with the named constants, and adds tests to make sure
that the changed code is covered in the test suite.
There are no changes to code. Additional tests are added,
so that the following 6 items now have 100% test coverage:
- Comment
- DefinedName
- DocumentGenerator
- IOFactory
- NamedFormula
- NamedRange
All other Samples write to temporary directory. DefinedNames samples
write to main directory, which (a) means they aren't stored with others,
and (b) they aren't ignored by git so look like changed files.
The tests are also simplified by requiring Header rather than Bootstrap,
making use of Helper.
* Improving Coverage for Excel2003 XML Reader
Reader/Xml is now 100% covered.
File templates/Excel2003XMLTest.xml, used in some tests, is *not*
readable by a current version of Excel. I have substituted a new file
excel2003.xml to be used in its place. I have not deleted the original
in case someone in future (possibly me) wants to see what it needs to
make it usable.
There are minimal code changes.
- Unused protected functions pixel2WidthUnits and widthUnits2Pixel
are deleted.
- One regex looking to convert hex characters is changed from a-z to a-f,
and made case insensitive.
- No calculation performed for "error" cell (previously calculation
was attempted and threw exception).
- Empty relative row/cell is now handled correctly.
- Style applied to empty cell when appropriate.
- Support added for textRotation.
- Support added for border styles.
- Support added for diagonal borders.
- Support added for superscript and subscript.
- Support added for fill patterns.
In theory, encodings other than UTF-8 were supported.
In fact, I was unable to get SecurityScanner to pass *any* xml which is
not UTF-8. Eliminating the assumption that strings might not be UTF-8
allowed much of the code to be greatly simplified.
After that, I added some code that would permit the use of
some ASCII-compatible encodings (there is a test of ISO-8859-1).
It would be more difficult to handle other encodings (such as UTF-16).
I am not convinced that even the ISO-8859 effort is worth it,
but am willing to investigate either expanding or eliminating
non-UTF8 support.
I added a number of tests, creating an Xml directory, and moving
XmlTest to that directory.
Pull Request had problems reading old invalid sample in the code
coverage phase, not in any of the other test phases, and not in
the code coverage phase on my local machine.
As it turns out, aside from being invalid, the sample
is much larger than any of the other samples. Tests have been
adjusted accordingly.
* Smaller Test File
Should eliminate need to avoid test during xml coverage.
* Break Up Style Test into Multiple Tests
Per suggestion from Mark Baker.
* Integrate AddressHelper Change
The introduction of AddressHelper introduced a conflict which needed to
be resolved. I wanted to test it locally before resolving. This required
me to add (unchanged) AddressHelper to my local copy. I hope this is
an okay manner of resolving the conflict.
* Weird Travis Error
XmlOddTest works just fine on my local machine, but Travis failed it.
Even worse, the lines which Travis flags don't even make any sense
(one was the empty line between two methods!).
This test is not essential to the rest of the change. I am removing
it from the package, and will attempt to re-add it when I have a chance
to sync up my fork with the main project.
* Initial work modifying the way named ranges are stored, and handled by the calculation engine
This should provide better support for:
- both union and intersection operators in composite named range values
- MS Excel implementation of the union operator duplicating values
- named formulae
- named ranges and formulae that reference other named ranges and formulae
- ranges and formulae that reference multiple ranges across multiple worksheets
* Initial work on handling defined names (named ranges and named formulae) correctly
- UTF-8 names (already extracted as a separate PR and merged)
- distinction between named ranges and named formulae
- correct handling of union and intersection operators in named ranges
- correct evaluation of named range operators in calculations
- calculation support for named formulae
- support for nested ranges and formulae (named ranges and formulae that reference other named ranges/formulae) in calculations
* Minor tweaks before resolving merge conflicts
* Fix extractSheetTitle() method to work on the last ! in a cell reference rather than the first
* Throw exception if a the reference to a defined name in a formula doesn't exist as a defined name
* Properly assess scope for defined names in calculation engine
* Elimination of some redundant code
* Minor tweaks to simplify entries o the stack where we need to check type
* Ensure correct scoping rules are applied when evaluating named ranges and formulae
* Adjustments to Gnumeric Reader for new defined names structure
* Initial work modifying the Ods Reader to handle named ranges, they weren't actually supported previously... this is still ongoing work
* Handle Ranges formatted as 3-d ranges, as long as the references are both to the same worksheet
* Additional testing for Named Ranges formatted as 3-d ranges, as long as the references are both to the same worksheet
* Skip composite named range tests for the moment
* Clean handling for `undefined name` exception when thrown in the calculation engine. Catch and replace with `#NAME?`
* Adjust method we use to determine whether a defined name is a range or a formula
* PHPCS Recommendations
* PHP doesn't support `mixed` yet, at least not at the minium version that we're working with
* More phpcs fixes
* More phpcs appeasements
* Final phpcs fixes for the moment
Still have a lot of echo and var_dump() statements in the code that scrutinizer will hate, but they stay for the moment while this is still WIP
* Please let this be the last of the phpcs fixes
* Unit tests to determine whether a defined name value is a range value or a formula
* phpcs appeasement
* Named tests from provider
* Initial steps for named ranges and formulae in the Ods Reader
* Reading pseudo-3d range addresses in Ods; treat second sheet reference as being identical to the first, which is the majority of cases where this will occur
* Initial work on Gnumeric reader for named ranges and formulae
* Suppress debug logging again
* Remove more debugging displays
* Last minor tweaks before phase two
* Minor refinements
* And all for the want of a space
* A little tidying up
* More tidying up
* phpcs fix
* Modify defined names in rebindParent()
* Renaming variables
* Resolve an issue with locally scoped defined names that don't contain any worksheet reference
* Keep phpcs happy
* Fix quote handling in regexp
* Fix a couple of scrutinizer issues
* Fix a couple of scrutinizer issues
* Update Xlsx Writer to work with the new defined name internal definition
Additional validation checks
* When adding new defined names through the readers, worksheet may not exist if we're only loading selected sheets rather than the full spreadsheet
* If the only thing that phpcs can pickup on is strings in double quotes instead of single quotes, then I know I'm getting close to ready
* Refactor Defined Names logic for Xlsx Writer into its own class
* phpcs keeping me on my toes
* Restore a couple of files that I managed to change without intending to
* Initial work on Ods Write to provide support for saving named ranges and formulae
* Resolve commas to semi-colons s argument separator when writing named formulae for Ods
* Extract Named Expression Writer for Ods into its own class
* Keep phpcs happy
* Refactoring of formula conversion when reading SpreadsheetML; preparation for reading named ranges because they will also need to use the same conversion method
* First pass at reading Named Ranges/Formulae from SpreadsheetML format xml files
* Remove unused namespace reference
* Defined names being written correctly for Xls; but not yet writing cell formulae that reference those defined names... that's the next big step
And I anticipate that defined names that reference other defined names will also be a problem
* Just to keep phpcs happy
... and yes, I know that there are still diagnostic echo statements in the code
* I had to miss some of the phpcs issues didn't I
* Work on the Xls Writer's Parser Tree to identify named range tokens in a formula, and to distinguish them from function tokens
* Still working on packing that d*** defined name reference in the writer
* Throw an exception in the Parser for saving Xls output if we encounter a defined name in a formula... writer will simply write the calculated cell value, and not the formula as at present
Strip out diagnostic output
* Some phpcs appeasement
* Fix a couple of Scrutinizer issues
* Additional verifications to differentiate a formula from a range value
Add explicit getters/setters for named ranges, named formulae and defined names
Additional unit tests
* Styling for closures
* Remove redundant docblocks
* Spaces
* Gah! Namespace use complaints
* Consistency of making calls to DefinedName rather than NamedRange; NamedRange should now be used only for Named Ranges, and should exclude Named Formulae
* Styling
* spurious newline
* No need to test for variable === null when we're typing it in the function argument definition
* Additional unit tests for local/global scoped named ranges and formulae; and a fix to getNamedFormula()
* Fix silly typo that led to breaking test
* Void return signature for unit tests
* Why weren't these picked up in the last pass?
* Refactoring of getNamedRange()/getNamedFormula()
* Eliminate unused constants, and defaults for private method parameters when always called with a value
* Use strict comparisons when comparing object hash codes
* Initial update to documentation for working with named formulae
* Fix for calculation of relative cell references in named ranges/formulae
* Fix current named range tests, because we should be using absolute references; tests for relative named ranges to be added later
* Fix for calculation of relative cell references in named ranges/formulae
* Updates to changelog and documentation for handling of absolute/relative references in named ranges
* Fix last remaining unit test with a named range reference
* Refactor formula conversion for Ods into a separate class; I hadn't realised that it previously wrote formulae as the MS Excel syntax without any conversion to Ods format
* Fix Ods Writer test xml to reflect Ods-native format for formula
* Docblocks
* Drop dollar prefix from Ods formulae and ranges unless it's necessary
* Set the formula convertor in the content writer constructor
* Documentation update
* Minor updates
* Remove var_dumps from file
* Fix the spurious single quote that was breaking named expressions in the Ods Writer... big sigh of relief that I finally spotted it
* Starting work on documentation for Defined Names, and some examples of using Named Ranges and Formulae
* Starting work on documentation for Defined Names, and some examples of using Named Ranges and Formulae
* Example of a relative named range for the documentation
* Mustn't have phpcs problems in sample code either
* More updates to the documentation
* That should conclude the documentation for Named Ranges, now time to move on to documenting Named Formulae
* That should conclude the documentation for Named Ranges, now time to move on to documenting Named Formulae
* PHPCS appeasement in sample code
* Initial documentation on Named Formulae
* PHPCS appeasements
* Additional comments in the documentation, and modify the named range name validation to support a \ as the first character in a name
* Fix breaking build
* Make defined names case-insensitive
* Fix case-insensitivity
* Improved documentation, and additional unit tests
* Additional unit tests, and a fix for removing a globally scoped defined name even if a worksheet is specified in the method call
* Fix unit test for removing named formulae
* Use assertCount instead of assertSame
* Forgotten voids
* Fix arguments for assertCount
* Unit tests for removing defined names, and a fix for removing locally scoped names
* Unit tests for absolute and relative named ranges in calculation engine, and fix an issue with worksheet name in the offset adjustments for relative references
* PHPCS Appeasement
* Additional unit tests, more documentation, and a fix to the calculation engine when no worksheet reference is provided with a named formula
* PHPCS appeasements
* Additional documentation and examples of using Named Formulae
* Additional examples to go with documentation
* A few minor phpcs appeasements
* Minor refactor of updateFormulaReferencesAnyWorksheet() method
* Discard an unused method argument
* Additional unit tests
* Additional unit tests
* Remove unused argument
* Stricter typing
* Fix return typehinting from remove named range/formula; should return the Spreadsheet object
* Use return typehint of self rather than explicit object type
* Redundant code just to keep scrutinizer happy
* Minor change to handle merge conflict
* phpcs fixes after merge
* Namespace usage ordering
* Please let this be the last phpcs fix needed
