Column Up

Yesterday, I was asked if I knew all three types of columns. I knew one and when I couldn't come up with the other two I felt dumb. I was assured knowing one put me ahead of game but I still felt dumb. So I'm polling you all.

Without cheating (no looking up the answer), do you know all three types of columns? You can just poost yes or no in the comments since I don't want to spoil it for anyone else :)
