Is there a way to "undo" a column deletion

So I'm new to using JChem and as I was poking around the software trying to figure out how to promote/hide columns I deleted a column. 

I did this by trying to delete a field and not un-checking the "also delete related column" check box since I didn't understand what it did at the time. 

So now I've been trying to figure out if there's a process for simply adding the column back into the table. If anyone could let me know how to do this or, at least, point me to the right place in the documentation that would be great.

No, I'm afraid that once you check that chcekbox and tell the database to delete the column then it is gone for good. You can add back a new column, but the data will be gone.

Thanks for the response. Glad I found that out before I deleted something important.
