Hi,
I wanted to keep the values of the right hand side table blank at first. It should show data only when I select any row from the left hand side table.
Create a parameter with a default value that does not appear in Col A. For example “Blank” or “Not Selected”
Optionally add the parameter to your sheet.
Then on table 2, create a filter for Col A, select Custom Filter, select Use Parameters, use the parameter you just created. Make sure the filter is set to “Only this visual”.
Again on table 2, create a custom action.
Set this to be a navigation action which navigates to the same sheet, but sets the parameter for Col A.
