java gridlayout 问题

想通过gridlayout分成左右两部分，两边各1个panel。但是最后只显示出一个。

JPanel panel = new JPanel();
panel.setBackground(Color.PINK);
panel.setLayout(new GridLayout(1, 2));

this.add(panel, BorderLayout.NORTH);

JPanel leftpanel = new JPanel();
panel.add(leftpanel, BorderLayout.WEST);
panel.setBorder(new TitledBorder("按钮"));

JPanel rightpanel = new JPanel();
panel.add(rightpanel, BorderLayout.EAST);
panel.setBorder(new TitledBorder("状态"));

Answer 1

既然panel使用了表格布局器，应该顺序依次添加就可以不用指定位置，
把panel.add(leftpanel, BorderLayout.WEST);改为panel.add(leftpanel);
把panel.add(rightpanel, BorderLayout.EAST);改为panel.add(rightpanel);试试

Answer 2

		JPanel panel = new JPanel();
		panel.setBackground(Color.PINK);
		panel.setLayout(new GridLayout(1, 2));
		JPanel leftpanel = new JPanel();
		leftpanel.setBorder(new TitledBorder("按钮"));
		panel.add(leftpanel);
		JPanel rightpanel = new JPanel();
		rightpanel.setBorder(new TitledBorder("状态"));
		panel.add(rightpanel);
		this.add(panel, BorderLayout.NORTH);
