I need to be able to hide cells in numbers on my iPad. My searching has shown that this cannot be done. Hiding cells is mandatory for spreadsheets as I, and I'm sure lots of other people, use them. Did apple simply forget to put this in their numbers app? If so, does anyone know how soon they will correct the problem. I tried to find an email address to contact apple, but after a few minutes got the impression they are out of reach.
