jtable添加行标题

将表格的第一列作为表头，使用渲染器改变其外观，看起来像表头 

        table.getColumnModel().getColumn(0).setCellRenderer(new RowHeaderRenderer());  

实现行标题

class RowHeaderRenderer implements TableCellRenderer   
{   
    private JLabel label = new JLabel();   
    // 获取表头的字体、前景色和背景色，用来将Label伪装成表头的样子   
    private static Font font = (Font) UIManager.get("TableHeader.font");   
    private static Color fgc = (Color) UIManager.get("TableHeader.foreground");   
    private static Color bgc = (Color) UIManager.get("TableHeader.background");   
    @Override  
    public Component getTableCellRendererComponent(JTable table, Object value,   
            boolean isSelected, boolean hasFocus, int row, int column) {   
        // TODO Auto-generated method stub   
        label.setFont(font);   
        label.setHorizontalAlignment(SwingConstants.CENTER);   
        label.setText(value.toString());   
        label.setOpaque(true);   
        label.setForeground(fgc);   
        label.setBackground(bgc);   
        return label;   
    }   
       
}
