title: Sorting Datatable in Descending Order
body: <p>I have a datatable with columns   Brand,Section,Color,Len.,Section Type,desc., Wt, Qty, Rate,Total,Storage,Action</p>
  
  <p>when I save data into the table i would like to get latest data at the top followed by older data i the datatable.Right now I am not getting the sorted data in the datatable even though I get them sorted properly from model and controller.</p>
  
  <p>My script looks like following:</p>
  
  <pre><code> $(document).ready(function(){
      $('#bar_list').dataTable( {
  
          "bProcessing": true,
          "bServerSide": true,
          "sAjaxSource": App.settings.basePath + "inventory/requisition/barlist"
          +"/type/&lt;?php echo $this-&gt;type; ?&gt;/id/&lt;?php echo $this-&gt;id; ?&gt;"
          +"/barFilterSection/&lt;?php echo $this-&gt;filterSection; ?&gt;"
          +"/barFilterColor/&lt;?php echo $this-&gt;filterColor; ?&gt;"
          +"/barFilterLength/&lt;?php echo $this-&gt;filterLength; ?&gt;"
  
      });
  </code></pre>
  
  <p>How to display the data in descending order in the datatable without specifying columns?</p>
