How to hide a Sub Form when there are no rows in table.

Hello Experts,

I am trying to build a Adobe Form , which displays data using multiple tables . And each table has its own Sub form .  I am trying to hide the whole sub form when the table has no records .

Can this only be done by writing a script on the Adobe Form or is there any other way to achieve this ?

I have tried writing different variations of java script to check if the table is empty and change the 'presence' of sub form to 'hidden' . But it does not seem to work .

I would appreciate your help or any code snippet on which can achieve this .

Thanks,

Rohit
