Google Chart Table Remove the selection

I am currently working with the Google chart tables. I have a problem with the selections. I want to turn the selections off, but it seems to be impossible. I even tried (an real ugly way) like an event listener on the select part that uses the method clearChart() to remove this.

Here is the test sourche code. Note that i cant use this in jsfiddle

<script type="text/javascript" src="https://www.google.com/jsapi" ></script>
<script type="text/javascript">
google.load("jquery", "1");

google.load('visualization', '1', {packages:['table']});

     function drawVisualization()
     {
          var data = google.visualization.arrayToDataTable([
          ['', 'Name', 'E-mail', 'Activated', 'Last login'],
          ['<input type="checkbox">', 'name1', 'name1@company.xxx', true, '20-07-2012'],
          ['<input type="checkbox">', 'name2', 'name2@company.xxx', true, '21-07-2012']

               ]);

               var options = {};
               options['showRowNumber'] = false;
               options['page'] = 'enable';
               options['allowHtml'] = true;
               options['pageSize'] = 18;
               options['pagingButtonsConfiguration'] = 'auto';

               var visualization = new google.visualization.Table(document.getElementById('table'));
               visualization.draw(data, options);
          }

          google.setOnLoadCallback(drawVisualization);

</script>
<div id="table"></div>

The problem is that if I use these checkboxes the (blue) selection is anoying and confusing.

Thanks.
