title: Delete and add datatables rows
body: <p>I'm updating datatables from a json response by clearing the table and adding the content again.</p>
  
  <pre><code>            var tbsorter = $('.tablesorter-js').dataTable();
              tbsorter.fnClearTable(); 
  
              var obj = JSON.parse(m);
  
              $.each(obj, function (key, value) {                 
                 var arObjData = value                    
                tbsorter.fnAddData(arObjData);        
             });   
  </code></pre>
  
  <p>I would prefer to only add and delete rows according to the json response and not clearing the table and then adding it all again.</p>
  
  <p>Is there a way to do that?</p>
