I have someone set as an admin for a workspace, but they cannot add new columns to sheets in there. Can only the owner add columns?
Only a licensed user who is a sheet Admin or owner can add columns to a sheet. If the person trying to add a column isn't a licensed/paid user, they'll see those options grayed out.
There's more info on licensed vs. unlicensed users in this article.
Tobrien,
The rules on this did change this last year if that is what is puzzling you?

Richard, if you're referring to free (unlicensed) users not being able to add columns, that change was made in December of 2014—two years ago.
Time flies, doesn't it?
