OK David that explains how to bring them back/unhide them, but how do I know they are there? For example, if I have 40 columns showing, how do I know 3 or 5 or 7 more are hiding? Do I need to go column by column (40 columns) and hover around and try to unhide additional columns that may or may not be hding nearby?
Any columns or rows that are hidden will show up next to 'Unhide' as a fly-out menu. You should be able to see all of the hidden rows or columns there.
For a survey I would like to hide the names and addresses (columns) of the participants. Is there a possibility to prevent the users who are NOT logged in to unhide these columns?
Thanks for your answer.
