How to check if the widget_table is empty?
type: item
description: Lets say I used WIDGET_TABLE created a table but not yet input any data. Then I tried to use "WIDGET_CONTROL, MyTable, GET_VALUE=MyValue" and expect MyValue should return an empty array. But instead, MyValue returned a 6 by 6 array. What is the right way to check if the table is empty? Thanks in advance. Sullivan
