GWT CellTable with ImageResourceCell

Question

Does anyone have an idea on how to implement a GWT CellTable with an ImageResourceCell from GWT 2.1M3?

I have the following but can't seem to figure out the correct way to add an ImageResourceCell

CellTable<DeviceInfo> ct = new CellTable<DeviceInfo>();
  // ct.setSelectionEnabled(true);

  ct.setSelectionModel(setSelectionModel(ct));
  ct.setPageSize(50);
  // listData.addView(ct);
  listData.addDataDisplay(ct);


  ct.addColumn(new TextColumn<DeviceInfo>() {

   @Override
   public String getValue(DeviceInfo devInfo) {
    return devInfo.getDeviceName();
   }
  }, "Name");

//THIS IS NOT WORKING

       ct.addColumn(new IdentityColumn<DeviceInfo>(new ImageResourceCell()) {

       @Override
       public String getValue(DeviceInfo devInfo) {
        return <Some imageResource>;
       }
      }, "Status");

Any help on this would rock! Thanks.
