One of our users have an a/b column to the left of the columns(a-..) and rows
(1-..)
Is there a way to turn this off. It is like a toggle columns. If you click
on a it will hide any rows that you have inserted and if you click b it shows
the rows that you added.

Not even sure what these extra a/b columns are called and I can't find
anything in the help?

Please Help!
