Fix #4485. VSTACK and HSTACK were introduced to Excel in 2024, and will now be supported by PhpSpreadsheet. Special thanks to @SlowFox71, who posted some code to implement VSTACK in the linked issue. I didn't have to change much between that version and the one in this ticket. Excel has at least one idiosyncrasy with these functions. If you try to stack 2 tables with, say, `=VSTACK(TABLE1, TABLE2)`, Excel will silently change it to `=VSTACK(TABLE1[], TABLE2[])` and all will be well. This would be difficult for PhpSpreadsheet to do. The problem is that, when Excel reads the formula without the square brackets, it calculates it as a `#NAME?` error. This is baffling, and all the more so because you can "correct" it by editing the formula *without changing anything*, hit enter, and the formula will magically work again. So, if you plan to stack tables using PhpSpreadsheet, you're probably best off using the square brackets.
