title: Display summation of columns in the footer of jqxgrid
body: <p>I need to display a footer row at the very bottom of the Jqxgrid, in which sum of the columns in the grid should get dynamically calculated as and when the values of the columns are getting in the grid.</p>
  
  <p>I am using a Keyboard Navigation Jqxgrid which is being present in the following link '<a href="http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/rowdetails.htm" rel="nofollow noreferrer">http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/rowdetails.htm</a>'. I checked out the API references for the same to try out this, but dint get any fruitful results.</p>
