How can I add a column to an existing table for text?

I created a table that is mostly dropdown. It's a scoring rubric. Now I want to add a column for text, so reviewers have an open-ended space to add their comments.

Hi, thank you for contacting JotForm support.

As per checking, it seems that you have already added a text column to the table.

Let us know if you need further assistance.

Yes, I figured it out and didn't have time to cancel my question. Thank you for following up.
