Sorry, I forgot to cast. Change the above to:

       TableCellRenderer renderer = super.getCellRenderer(row,col);

       int alignment = (col == dataModel.getColumnCount() - 1) ?
               SwingConstants.CENTER : SwingConstants.LEFT;

       ((JLabel)renderer).setHorizontalAlignment( alignment );
       return renderer;

Should work (but not tested).

Bye
Michael
