title: DataTables TableTools buttons not working correctly (simple example)
body: <p>I am trying to use the newest tableTool 2.2.0 and i have made a little and simple example <a href="http://jsfiddle.net/9ZTGb/" rel="nofollow">jsfiddle.net/9ZTGb/</a></p>
  
  <p>COPY and PRINT buttons seems to respond, but the "Copy" is resulting "blank", and "CSV","Excel","PDF" seems not workinkg at all..</p>
  
  <p>this is the table:</p>
  
  <pre><code>&lt;table id="tblExport" class="table table-condensed"&gt;
      &lt;thead&gt;
          &lt;tr&gt;
              &lt;th&gt;#&lt;/th&gt;
              &lt;th&gt;First Name&lt;/th&gt;
              &lt;th&gt;Last Name&lt;/th&gt;
              &lt;th&gt;Username&lt;/th&gt;
              &lt;th&gt;Status&lt;/th&gt;
          &lt;/tr&gt;
      &lt;/thead&gt;
      &lt;tbody&gt;
          &lt;tr&gt;
              &lt;td&gt;1&lt;/td&gt;
              &lt;td&gt;Larry&lt;/td&gt;
              &lt;td&gt;Smith&lt;/td&gt;
              &lt;td&gt;@lsmith&lt;/td&gt;
              &lt;td&gt;Approved&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;2&lt;/td&gt;
              &lt;td&gt;Mark&lt;/td&gt;
              &lt;td&gt;Williams&lt;/td&gt;
              &lt;td&gt;@mwills&lt;/td&gt;
              &lt;td&gt;Pending&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;3&lt;/td&gt;
              &lt;td&gt;Jeremy&lt;/td&gt;
              &lt;td&gt;Jones&lt;/td&gt;
              &lt;td&gt;@jj&lt;/td&gt;
              &lt;td&gt;Success&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;4&lt;/td&gt;
              &lt;td&gt;Carlos&lt;/td&gt;
              &lt;td&gt;Martin&lt;/td&gt;
              &lt;td&gt;@cmar&lt;/td&gt;
              &lt;td&gt;Suspende&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>and this is the js script:</p>
  
  <pre><code>$(document).ready(function () {
       $('#tblExport').dataTable({
           "sDom": 'T&lt;"clear"&gt;lfrtip',
               "oTableTools": {
               "sSwfPath": "https://datatables.net/release-datatables/extras/TableTools/media/swf/copy_csv_xls_pdf.swf",
                   "aButtons": ["copy", "csv", "xls", "pdf", "print"]
           }
       });
   });
  </code></pre>
  
  <p>I would really appreciate if someone could tell me why it isn't working. the example here and the jsfiddle i tried to make as simple as possible, but still not really working.. </p>
