General Preferences

The General section of the Set Preferences dialog contains general user preferences, such as allowing tables resulting in 0 rows from a selection.

Allow 0 row tables when the macro is annotated with <meta>empty<meta>
When selected, this allows selections resulting in tables with 0 rows, if the macro contains <meta>empty<meta>.

If this is not selected (or if this is selected, but the macro does not contain the empty <meta> element), the user will receive an error saying that no rows were selected.
