title: Datatable with Scroller not working
body: <p>Using the last version of DataTable (1.10.9) and the scroller widget (1.3.0), I can't make it work with this simple piece of code:</p>
  
  <pre><code>                    var data = [{'a': 'a', 'b': 'b'}, {'a': 'c', 'b': 'd'}];
                      var columns = [{'title': 'a', 'data': 'a'}, {'title': 'b', 'data': 'b'}];
                      $("#mytable").DataTable({
  
                          "processing" : true,
                          "filter": false,
                          "orderClasses": false,
                          "ordering": false,
                          data:           data,
                          deferRender:    false,
                          scrollY:        400,
                          scrollCollapse: true,
                          scroller: {
                              loadingIndicator: true
                          },
                          dom: "rtiS",
                          columns: columns,
                      });
  </code></pre>
  
  <p>As a result, I have an empty table with message "Showing NaN to -Infinity of 2 entries". WIthout the scroller widget, it is working fine (but I need it).</p>
  
  <p>What did I miss?</p>
