title: How to hide jqGrid footer row when no records present
body: <p>I am using footer row to display Total of Amount column. If 0 records are found, I display message: "There are no records. If you would like to add one, click the "+" button below."
  However the footer row is still shown with empty cells.</p>
  
  <p>I tried method clearGridData as</p>
  
  <pre><code>grid.jqGrid("clearGridData", true).trigger("reloadGrid"); 
  </code></pre>
  
  <p>However that doesn't work. Shall I instead use  </p>
  
  <pre><code>$(".ui-jqgrid-ftable").css('visibility', 'hidden'); 
  </code></pre>
  
  <p>OR you have any better recommendation?</p>
  
  <p>Regards,</p>
