Tables: Fixed an issue where user's Y cursor movement within a hidden column would have side-effects.

- Afaik the "to allow ImGuiListClipper to function" was added early during Tables development (prior to commit 55) and later replaced by support in ImGuiListCipper, it seems unnecessary.
- Also removed RowPosY2 being accted in TableEndCell().
+ Comments about 2bb9e35 + fix example bb224c8
