How can I force the columns in a Tkinter application window to be of equal width? The tkdocs website states as follows: The width of each column (or height of each row) depends on the width or height of the widgets contained within the column or row.

But when I run it on my windows machine, it fails. I also tested on several other machines (include windows and linux), it failed all the time.
