Hi Sriyashis,
My apologize that i did not understand your issue correctly.
You are using fixed table with one header ( title) and 6 rows(table content)
You want to hide the table row(s) if the content is lesser than 6 ; or you want display table according to the size of the table content.
This tutorial shows steps on how to create a table in Adobe Form, according to the size of the content.

Or, you can refer to the tutorial mentioned by Rakesh above, you will have flexibility to display/adjust fields in a row .

Hope this helps.
