title: Add JSON data to datatable
body: <p>I want to add JSON data to a existing datatable.</p>
  
  <p>The JSON data looks like this:</p>
  
  <pre><code>[
      ["Trident","Internet Explorer 4.0","Win 95+","4","X","X"],
      ["Trident","Internet Explorer 4.0","Win 95+","4","X","X"],
      ["Trident","Internet Explorer 4.0","Win 95+","4","X","X"],
      ["Trident","Internet Explorer 4.0","Win 95+","4","X","X"]
  ]
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>$('#' + tab + '_table').dataTable().fnAddData(data);
  </code></pre>
  
  <p><code>data</code> is holding the JSON data.</p>
  
  <p>Anything seems wrong there since it adds only one row with this:</p>
