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().
