body: <p>I need to show the Display number of records in a page by using datatables plugin.
  I have included the following js files:</p>
  
  <pre><code>js/jquery.dataTables.js
  js/ColVis.js
  js/ColumnFilterWidgets.js
  js/extras/TableTools/media/js/ZeroClipboard.js
  js/media/js/jquery.dataTables.js
  js/extras/TableTools/media/js/TableTools.js
  </code></pre>
  
  <p>and code is like:</p>
  
  <pre><code>oTable = $('#data-table').dataTable( {
           "sDom": 'CT&lt;"clear"&gt;firtlip',
          "oTableTools": {
              "sSwfPath": basePath+"/js/extras/TableTools/media/swf/copy_csv_xls_pdf.swf",
              "aButtons": [ {"sExtends": "csv","sFileName" : curpath+".csv","sButtonText": "Save to CSV","mColumns": "visible"} ]
          },
         "aaSorting": [[0, "desc"]],
         "bAutoWidth":false,
         "aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
         "iDisplayLength": 10,
         'sPaginationType': 'full_numbers'
      } );
  </code></pre>
  
  <p>But the select box for for selecting the number of records is not displaying.
  Please guide me where is the issue.
  Thanks in advance.</p>
