请高手帮忙 怎么修改JTable的排列方式?

Question

直接写个render:
class MyRenderer extends DefaultTableCellRenderer{
  public Component getTableCellRendererComponent(JTable table,
                            Object value,boolean isSelected,boolean hasFocus,
                            int row,int column){
        if(column == 2){
          setHorizontalAlignment(JLabel.LEFT);
        }else {
         setHorizontalAlignment(JLabel.RIGHT);
        }
    return super.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
  }
