  Well I got a little further and discovered a possible bug maybe ? The scenario i'm working with creates a number of datatables which are initially hidden . One is selected from a menu and is displayed .. The TableTools buttons are displayed but not active .. I tracked the problem to a function getDOMObjectPosition in dataTables.tableTools.js ..

  getDOMObjectPosition: function(obj) {
          // get absolute coordinates for dom element
          var info = {
              left: 0,
              top: 0,
              width: obj.width ? obj.width : obj.offsetWidth,
              height: obj.height ? obj.height : obj.offsetHeight
          };
  

  It seems that if the dataTable is initially created in a hidden state then the obj.width is undefined so the offsetWidth is used and this is 0 .. The result is that the buttons are displayed BUT aren't active due to the generated swf buttons having 0 height and width - changing these manually in firebug enables the corresponding buttton and enables the button .

  <div style="position: absolute; left: 0px; top: 0px; width: 0px; height: 0px; z-index: 99;"><embed id="ZeroClipboard_TableToolsMovie_1" src="../swf/copy_csv_xls_pdf.swf" loop="false" menu="false" quality="best" bgcolor="#ffffff" width="0" height="0" name="ZeroClipboard_TableToolsMovie_1" align="middle" allowscriptaccess="always" allowfullscreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" flashvars="id=1&amp;width=0&amp;height=0" wmode="transparent"></div>
  

  Is this a bug ? Anyone suggest a workaround ? Thanks

  If the table is hidden initially, then you need to call the fnResizeButtons method when it is made visible so the Flash movie can be made to fit the button area.
