title: Setting default sorted column in Datatable
body: <p>I am working on datatable plugin in Jquery. And have to set the default column by which the data is sorted so I mean that :</p>
  
  <p>I have a table with 4 columns and by default the data is sorted by column no 1, I want that the data should be sorted by column number 2 or 3.</p>
  
  <p>How that can be done:</p>
  
  <pre><code>$('#tblMainTable').dataTable({
      "bJQueryUI" : true,
      "sDom" : 'R&lt;"H"lfr&gt;t&lt;"F"ip&lt;',
      "aoColumns" : [ 
          {"bSortable" : false}, 
          null, 
          null,
          null,
          {"bSortable" : false}, 
          {"bSortable" : false}
      ],
      "aaSorting": [[ 2, "desc" ]]
  });
  </code></pre>
  
  <p>I specified that in "aaSorting" but not getting the result.</p>
  
  <p>Please shed some light?</p>
