How do you adjust the column width for the row number in Variables?

I can adjust the Columns that have numbers, but the one that has the row number. Reference the image. Now, I can see the row numbers on this one, but sometimes I cannot. Thanks.

No idea what talking about; whatever image didn't get attached; much better would be to attach actual data that illustrates the issue of what you have, what you tried, what you expect (and why/how do we know that's what is wanted?).
