Table Manager: The program crash[BUG LOGGED]

I was working for the construction of a model sheet of the script, when after inserting a table and wrote the text within, as I was entering the background color of the program crashed and closed and when I restarted appeared against a black background with loss of text.
I attach the image to give an idea of what has happened.
It would be nice if potenziaste for the future management of the tables.
Thank you for your attention.

I continued to test the insertion table, and I found that the crash occurs systematically.
Specifically, when I insert the table shows the default 2 rows and two columns.
At a time when I want to reduce a column of the program crashes and closes.
I enclose a check for a clearer picture of the problem.
Thank you for your attention
