* 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
* Update Some Doc Block Annotations
See PR #2010. That PR was never completed, and has gone stale. However, it was correct in identifying a situation where the doc block was not entirely accurate. It did not go far enough - several closely-related methods have similar problems. This PR attempts to fix the original problem and its close relations. Aside from the doc block changes, there are very minor changes to executable code. It also changes some of the unit tests targeted at the methods in question to eliminate mocking in favor of 'real' tests.
* Change Method to Static
Otherwise Scrutinizer will complain, even though Phpstan doesn't.
* Scrutinizer
Various clean-up activities.
* Scrutinizer
@#&$(*#&$ Got complexity down from 53 to (I think) 50. Don't really know what the target is.
* Code Changes Suggested By Review
Some improvements suggested in review by @PowerKiKi.
* Update Cells.php
* Merge Conflict
A change to a parameter name caused several problems when trying to fix it on Github. Fixing it locally should do the trick.
* Merge Conflicts in Phpstan Baseline
PR #2382 made a large number of changes to Phpstan Baseline, some of which conflicted with the Phpstan Baseline changes in this PR. This should resolve them all.
#1495 reports that ActiveSheet can change when calculation
involves jumping around between sheets.
Save index before calculation, restore after, add test.
