I am using [DataTables](http://datatables.net/ref) and the [TableTools](http://datatables.net/extras/tabletools/) add-on. I want to use [TableTools](http://datatables.net/extras/tabletools/) with a blank column to export a pdf version of the table. Using [fnRender](http://datatables.net/ref#fnRender)

```
$('#example').dataTable({ 
  'mDataProp':null, 
  'sTitle':'Date',
  'fnRender':function (oObj) {
       return oObj.aData.date.substring(0, 10);
   }
});

```

without [fnRender](http://datatables.net/ref#fnRender) , TableTools works well (of course)

sugestões?
