Just a thought, but maybe putting a button to export table data would be a good idea.
Using an ArcGIS Service and getting map data from an app online and when I click on Show table, it shows the first few columns of the table, but when I try to select all the data to copy & paste into excel, it keeps auto-refreshing so i can't select it and there is no export table data.
This is an awful design and should be re-thought.
