Description:
When I delete columns after my last populated column Calc removes formatting from the columns before the deleted columns.

Steps to Reproduce:
1. Create a new file and create a simple table with some formatted headers and values in the rows below it - doesn't matter what - as long as there is formatting applied (e.g. background on cells, bold text, etc.)
2. Select the column next to the table
3. Delete the selected column
4. Select cell A1
5. Select the last populated cell


Actual Results:
Formatting gets corrupted

Expected Results:
Existing formatted cells should be unaffected by deleting unpopulated columns.


Reproducible: Always


User Profile Reset: Yes

Additional Info:
Deleting rows does not seem to have the same problem.
