Description:
I created a table with 5 columns, and a style for each column. When I got to the end of the table and hit the TAB key on the last cell to create a new row, all of my text formatting reverted back to the default "Table Contents" style. The text in the rows showed that my style were still applied and the attributes of those styles had not changed, but what actually appeared was the default Table Contents style. Reapplying my styles to each row caused them to go back to the desired format, but each new table row caused the problem all over again.

Steps to Reproduce:
1. Create a table with a few rows
2. Add text to the cells, format them and create styles
3. On the last cell, hit the TAB key to create a new row.

Actual Results:  
The text formatting is all lost

Expected Results:
A new row would be created which, at the very least, would not affect cells already filled.


Reproducible: Always

There were other events which triggered the same problem, but I can't remember what they were. The new row creation caused the problem every time.
