JTable实现设置单个单元格颜色

Swing JTable没有提供设置单个单元格颜色的API,可通过重写DefaultTableCellRenderer类的 getTableCelllRendererComponent实现。核心代码如下：

 class MyTableCellRender extends DefaultTableCellRenderer(){
             private Color color = getBackground();
             
             @override
             public Component getTableCelllRendererComponent (JTable table, Object value,
              boolean isSelected, boolean hasFocus, int row, int column){
                  Component c = super.getTableCellRendererComponent(table,value,isSelected, hasFocus, row, column);
                  if("拒绝".equals(value) && column == 5){
                    setBackground(Color.red)//如果第五列的值为“拒绝”则背景颜色设置为红色
                  }else{
                    setBackground(color);//其他单元格颜色不变
                  }
              return c;
             }
         }
