How to remove duplicate rows from a dynamically generated table

I am building a table of data and this data is combined data from two SharePoint lists.

At the end I applied the code below to remove the duplicate rows, but it is not doing the job. Any alternative code I can use?

 var seen = {};
          $('table tr').each(function() {
          var txt = $(this).text();
         if (seen[txt])
            $(this).remove();
        else
           seen[txt] = true;
        });
