This is something you can try:
Hide the rows you want hidden.
Unlock the cells that need to be edited.
Then protect the sheet so that it will not changed.

Very simple question: I have a "shared" workbook that contains many hidden
rows. For a few days, those rows remained hidden, but for some reason the
sheet is now loading with those rows now visible and I don't understand why.
Please help. I just want these to be hidden pretty much forever. Thanks in
advance.
