Description:
If I add a table in writer and edit it with different fonts and bold etc, then inserting a row resets all formatting in the table.  I tried editing the "table contents" style but it resets to the default style not the edited one even though I did not change the name of the style.

Steps to Reproduce:
1.Create Writer document in osx
2.insert and edit table
3.insert row into table

Actual Results:  
The contents of the table revert to default formatting, even if table contents style has been edited

Expected Results:
A row is inserted and the rest of the table contents is unaffected


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
