BUG when you decrease no of columns


I found program crashing when I tried to decrease no of columns. The routine is as followed:

  1. I have made table with 10 rows and 5 columns; mostly with empty cells
  2. I have selected last column
  3. I have tried to change no of columns from 5 to 4
  4. program crashed

I repeated the same routine and the program crashed again.

I think it’s bug.
