set tabletags= { on | off}

Controls the display of tables. When set to off, the tags that define table structure are hidden (regardless of the current tag display) and a graphical representations of tables appear in the edit view. When set to on, this graphical structure is hidden.

If the current tag display (set tagdisplay command) is set to full or partial, you will see the tags that define a table's structure. If set tabletags is set to on and the current tag display is set to none, only the content of the table will be visible.
