title: Removing a column with table editor components
body: <p>I have a table that includes several columns with check boxes in them. Occasionally, my code needs to remove the columns and create new ones. When I do this via the following code</p>
  
  <pre><code>int columnscount = myTable.getColumnCount();
  
  //remove the columns
  for(int i=2;i&lt;columnscount;i++){
      myTable.getColumn(2).dispose();
  }
  </code></pre>
  
  <p>All the columns are removed but the checkboxes are not. How do I remove the editor components? They are created using this code</p>
  
  <pre><code>TableEditor editor = new TableEditor (myTable);
  editor.minimumWidth = checkButton.getSize().x;
  editor.horizontalAlignment = SWT.CENTER;
  editor.setEditor(checkButton, ti, colCheckCount);
  </code></pre>
