How can I delete a column on a table?

I watched the "Tables" webinar last night and added a column to one of my tables as a test figuring I could delete it afterword. I can't figure out how to delete a column from a table.

Hi,

You can hide the column or manage the column. Please check the screencast below on how to do that:

Hi,
So I cannot delete a column I created using the "Tables" interface.
That said I should always use the "Forms" interface to add columns so
that I can delete if I want to.

Hello Richard - You can delete any columns you want in the table that you created.

But for the default SUBMISSION TABLE of the form, the pre-added columns are associated with each field of the form, so you would need to remove the field from the form to delete its corresponding column in the Submission table.
