How to show only pages with some data in BIP?

I created a .rtf file that has one table. My conditions for showing data: create a section for each table and don't show pages if there is no data in the table.

So far I have done this:

<?if:COL1!='' or COL2!='' or COL3!='' or COL5!='' or COL6!='' or COL7!=''?>
<?for-each@section:G_1?>
TABLE
<?end for-each?>
<?end if?>

      

        
        
        
      

    

As a result, I have blank pages and pages that have data one by one, depending on the data. How can I remove these blank pages? Pls help!
