I would like to have a button on each of several sheets in a work book, assigned to a macro
that would "Hide & Unhide" columns in a workbook each time it is clicked.

For example; It would hide say columns E G I K M O When clicked, (when open all would be 2.5 wide in size)
Then with another click, Unhide the same columns. (Columns visible would always need stay / be 2.5 wide)
Can this be done? Can some one show me the macro?

Thanks
