title: Jdatepicker not working in jtable
body: <p>I have used <code>DatePickerCellEditor</code> for a cell in <code>Jtable</code>. When I select a date from the popup calender, the date with <code>dow mon dd hh:mm:ss zzz yyyy</code> format is displayed. I want to change it to date format (<code>yyyy-MMM-dd</code>). 
  <br>I did try doing by:</p>
  
  <pre><code>DateFormat formatter ;
  
  formatter = new SimpleDateFormat("yyyy-MMM-dd");
  
  DatePickerCellEditor datePicker = new DatePickerCellEditor(formatter);
  
  TableColumn po_date = tableModel.getColumnModel().getColumn(1);
  
  po_date.setCellEditor(datePicker);
  </code></pre>
  
  <p>But it didn't work. Can anyone help me with this one?</p>
