How can I change the column headings to the table widget?

Rather than the table headings showing 'A', 'B', 'C' etc. Can i add in actual headings?

To change the column headings, simply select the field and click on the Columns button. Simply enter the headings that you would like to use and click OK to save it.

However, I checked your form and it appears that you were already able to change the column headings successfully.
