title: reload a loaded jqGrid with a different table data
body: <p>I have a page that displays a table in two different modes. In each mode I have a different set of columns. I'm using jqGrid to display the table. When I try to load the table for the second time (with same or different columns for that matter) the table will not refresh the data.</p>
  
  <p>Is there a different API to reload data? Or should I use some method to clear the table first?</p>
