Table layout formatting

I want to present a list of people in table format. So in the elements visibility section, I chose to show and hide the appropriate items, but no matter what I do, the ‘standard’ column headers are shown which are thumbnail, name, designation, details and social links. For example, i chose to hide thumbnail, but still the column header text “Thumbnail” is shown. In that column is the name because everything shifts over.

How can i define the column headers I want via the shortcode builder?
