Hi Ken,

 

One more  issue is there.

 

Steps to reproduce

 

1. Create a table having 4 columns and some rows

2. merge column2 and column3

3. place cursor on the second column and click on insert column left button, it will change the layout

4. also, place cursor on first column and click on insert column right button, again it will change the layout
