带有行标题的JTable

/**
 * @author chega
 * this class extends JTable and has two sub JTable class in it ,they are:RowHeadTable and LeftTopCornor,they are also JTable, 
 * RowHeadTable is the rowHeadView of JScrollPane ,and LeftTopCornor is the upper-top cornor of JScrollPane, you can use 
 * TableWithRowHead like this:<br/>
 * <b> 
 * 
 * JScrollPane pane = new JScrollPane(table);<br/><br/>
 * pane.setRowHeaderView(table.getRowHeadTable());<br/><br/>
 * pane.setCorner(JScrollPane.UPPER_LEFT_CORNER, table.getLeftTopCornor());<br/><br/>
 * </b>
 * If you select a row in RowHeadTable ,then the row at the same row index of TableWithRowHead will also be selectd,so vice-verse
 * if you select the only row in LeftTopCornor , the all rows in TableWithRowHead and RowHeadTable will be selected.
 * <br/>
 * for some reason , the LeftTopTable and RowHeadTable set selectionBackground to white, you can also set it to other new value, but 
 * some details should be considered.
 * <br/>
 * <br/>
 * <b>Attention:</b>
 * some method should not be invoked:table.setRowHeight() and table.getTableHeader().setHeight(),
 * alternative methods are supplied:setTableRowHeight() setTableHeadRowHeight().

ps:最后那个LeftTopCornor直接用一个JCheckBox就可以了。
