Description:
If you enter something in a cell of the spreadsheet (for example, A1) which exceeds the cell border and there's no content in the cell to the right of it (for example, A2), the border between the two cells does not disappear automatically. You have to merge both cells to remove the cell border. This is annoying.
If you then change something so that the content of A1 does not exceed the border anymore (if both cells had not been merged) and you want to enter something in A2, you have to unmerge it again.
I'd be very happy if you could fix that. :)

Steps to Reproduce:
Enter something in A1 which exceeds the size of the cell.
A2 has no content.

Actual Results:
Cell border doesn't disappear automatically.

Expected Results:
Cell border disappears automatically.


Reproducible: Always
