title: Ids get ordered alphabetically instead of numerically
body: <p>I am pulling out data from MySQL ordered by id, which is 1,2,3 and there is no problem.</p>
  
  <p>However when I use it with <a href="http://www.datatables.net/" rel="nofollow noreferrer">http://www.datatables.net/</a>, the order becomes 1, 10, 11 ,12,..</p>
  
  <p>I am not able find any parameter to sort this problem.</p>
  
  <p>I am wondering if anyone knows how to fix this.</p>
  
  <pre><code>$(document).ready( function() {
      $("#tablesorter").dataTable( {
          "iDisplayLength": 40,
                  "oLanguage": {
              "sLengthMenu": 'Display &lt;select&gt;'+
                  '&lt;option value="20"&gt;20&lt;/option&gt;'+
                  '&lt;option value="40"&gt;40&lt;/option&gt;'+
                  '&lt;option value="60"&gt;60&lt;/option&gt;'+
                  '&lt;option value="80"&gt;80&lt;/option&gt;'+
                  '&lt;option value="100"&gt;100&lt;/option&gt;'+
                  '&lt;option value="-1"&gt;All&lt;/option&gt;'+
                  '&lt;/select&gt; records'
          }
      } );
  } )
  </code></pre>
