Can't unhide a column

[Deleted]

Windows 10

My column C which I hid last week now won't unhide. I've tried right-clicking unhide, select all unhide, visibility, reformatting all the column widths: nothing works.

If you do this:
Press F5, type C:C, click OK and then select (Start tab) Format, Column width and set it to e.g. 10, does it show?
is View, Freeze panes set by any chance?

I followed your suggestion and went to View. Freeze panes. Cleared all and voila! column A re-appeared.

Kisses @Jan Karel Pieterse - it was freeze panes for my file.  I would not have found it without this thread.

Freeze Panes...great tip! It works for me too after far too much time scouring help threads. Thank you!!!
