Deleting table column leaves wrong rowspan

[Jakub Ś]

Steps to reproduce

1. Create 3x3 table
2. Split middle cell in middle row horizontally
3. Delete middle command

Expected result

Rowspan created for cells in second row should be removed

Actual result

Rowspan created for cells in second row is not removed. This will break table layout once you start adding new rows. Please try tabbing after deleting the column. When new row is created the layout gets broken.

Other details (browser, OS, CKEditor version, installed plugins)

Very similar issue to #6618

[Jakub Ś]

In 2x2 table there are rowspan="2" and empty row left (<tr></tr>). If however you add column and start adding new rows with tab, you will get layout broken in exactly the same way.
Please see attached video for this issue.
