Now that it is possible to create and delete columns and rows in a table in Visual Editor (thank you!) can you please create a method to re-arrange the order of the columns and rows?

Either a 'handle' system that lets you 'drag' the column/row, or a 'move 1 row up/move 1 row down' button (adjacent to the current 'insert before/insert after' options), would be viable methods.
