实现SWT中Table单元格的可编辑

public void editorTable(Table table,Event e){
  final TableEditor editor = new TableEditor(table);
  editor.horizontalAlignment = SWT.LEFT;
  editor.verticalAlignment=SWT.LEFT;
  editor.grabHorizontal = true;
  Rectangle clientArea = table.getClientArea();
        Point pt = new Point(e.x, e.y);
        int index = table.getTopIndex();
        while (index < table.getItemCount())
        {
         boolean visible = false;
         final TableItem item = table.getItem(index);
         for (int i = 0; i < table.getColumnCount(); i++)
         {
          Rectangle rect = item.getBounds(i);
          if (rect.contains(pt))
          {
           final int column = i;
           final Text text = new Text(table, SWT.NONE);
           Listener textListener = new Listener()
           {
            public void handleEvent(final Event e)
            {
             switch (e.type)
             {
              case SWT.FocusOut:
               item.setText(column, text.getText());
               text.dispose();
               break;
              case SWT.Traverse:
               switch (e.detail) {
                case SWT.TRAVERSE_RETURN:
                 item.setText(column, text.getText());
                case SWT.TRAVERSE_ESCAPE:
                 text.dispose();
                 e.doit = false;
               }
              break;
             }
            }
           };
           text.addListener(SWT.FocusOut, textListener);
           text.addListener(SWT.Traverse, textListener);
           editor.setEditor(text, item, i);
           text.setText(item.getText(i));
           text.selectAll();
           text.setFocus();
           return;
