TOCOL and TOROW were introduced to Excel in 2024, and will now be supported by PhpSpreadsheet. The documentation says that, under certain circumstances, "blanks" will be ignored. This seems demonstrably wrong. In the right circumstance, Excel will ignore nulls, not blanks. Further, when it decides to not ignore the nulls, it changes them to 0, which also seems insufficiently documented. PhpSpreadsheet will behave as Excel does.
I discovered some minor problems and some missing test conditions for the TRANSPOSE function while testing these. Those are now fixed.
While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Start refactoring the Lookup and Reference functions
- COLUMN(), COLUMNS(), ROW() and ROWS()
- LOOKUP(), VLOOKUP() and HLOOKUP()
- Refactor TRANSPOSE() and ADDRESS() functions into their own classes
* Additional unit tests
- LOOKUP()
- TRANSPOSE()
- ADDRESS()
