UP 有人帮忙看看吗？ 上面的代码调试完毕，可以执行。

就剩下一个 布局 的问题了，帮帮忙吧。

问题： 如何把它做成一个构造函数的形式？
我试了一下，独立（做成一个构造函数的形式）后，scrollPane.getColumnHeader() 总为空？为什么？
（合成上面的形式，就没有问题了。）

把 JFrame frame 独立出去（我想把它放在 Main函数里 ）

如何做呀？

可是还有一个疑问，如何把它做成一个构造函数的形式？
在主程序中，用如下的方法调用？　请大家帮忙。谢谢

public static void main(String[] args) {
JFrame frame = new JFrame("Test");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});

frame.setBounds(30, 60, 780, 250);
frame.getContentPane().setLayout(null);
final MultiSpanHeaderColorTest panel = new MultiSpanHeaderColorTest ();
panel.setBounds(0, 0, 764, 184);

frame.getContentPane().add(panel);

frame.setVisible(true);
}
