When the source of a table is appsheet, it feels weird to be adding columns in the appsheet table view and then flipping over to the appsheet data/column view to edit fields. It would be nice to have delete column and insert columns available on the data/column page so that the table can be fully designed in the data/column view. I envision this as buttons that appear alongside the View Data Regenerate buttons. Of course, they would only appear here if appsheet is the data source.
