Description:
A table completely loses its format when doing some edits. The format is lost (not reverted to the original autoformat) and this can not be undone

Steps to Reproduce:
1. open a new Writer document
2. insert a table from Table > Insert table
3. change the format (eg colors, font, etc. etc.)
4. Now erase one row

Actual Results:
the table changes to a random-ish format. There is no undo

Expected Results:
the row should be erased without affecting the format. And the action should be 'undoable'


Reproducible: Always
