I want to protect the locked cells in any given spreadsheet so that the user cannot override formula cells. I have also grouped columns that contain historical information. When I protect
the sheet, I cannot expand or collapse the grouped columns. I have tried checking boxes when in the protection dialogue box such as "Format columns", with no success. I use Excel 2007, but it is saved as a 2003 file because some users are still with that
version.
Is it possible to expand or collapse grouped columns when a sheet is protected?
