A family of Microsoft word processing software products for creating web, email, and print documents.
Aha! I found a solution to my problem. I have my page set up for duplex, therefore different odd and even pages and mirror margins. I found that I can adjust table columns just like always when it's on the ODD page, but as soon as I try to adjust anything on the EVEN page, they don't work no matter what I do.
My solution was to insert a page break to force to an odd page, adjust table, then remove my page break.
Does anyone else have this issue? If so, did you find a better way to solve it? I'm using Word 2016, though I have had the trouble in the past, however I hadn't connected it to duplex page setup, so I'm not certain that it was the issue while using 2010 or 2013.
