如何更改jTable中选定单元格的背景？

我已经编写了表格渲染，但它分配了所有行，并且看不到现在选择的单元格类型。

public class MyTableRanderer extends DefaultTableCellHeaderRenderer{

    @Override
    public Component getTableCellRendererComponent(JTable jtable, Object obj,
            boolean isSelected, boolean hasFocus, int row, int col) {
        setText(obj.toString());

        if(isSelected){
            setBackground(Color.ORANGE);
            setForeground(Color.BLACK);
        } else {
            setBackground(Color.WHITE);
            setForeground(Color.BLACK);
        }

        return this;
    }

}

编辑:

public class MyTableRanderer extends DefaultTableCellHeaderRenderer {

    @Override
    public Component getTableCellRendererComponent(JTable jtable, Object obj,
            boolean isSelected, boolean hasFocus, int row, int col) {
        setText(obj.toString());

        Component cell = super.getTableCellRendererComponent(
                jtable, obj, isSelected, hasFocus, row, col);


        if (isSelected) {
            setBackground(Color.ORANGE);
            cell.setBackground(Color.green);
            setForeground(Color.BLACK);
        } else {
            setBackground(Color.WHITE);
            setForeground(Color.BLACK);
        }

        return this;
    }
}

I have already written table-rendering, but it allocates all row, and do not visible what kind of cell selected now

然后需要测试这两种方法if (isSelected & hasFocus) {
