java - Java gridbaglayout グリッドの配置の問題

Question

GridBagLayout でいくつかの問題が発生しました。写真を投稿できなくてすみません。それが私が欲しいものです：

  0 1 2 3 4
0 1 1 1 1 2
1 1 1 1 1 2
2 1 1 1 1 2
3 1 1 1 1 4
4 3 3 3 3 4

そして、それは私が得るものです

  0 1 2 3 4
0 1 1 1 1 2
1 1 1 1 1 2
2 1 1 1 1 2
3 1 1 1 1 2
4 3 3 3 3 4

次のコードが使用されます。

    JPanel mainPanel = new JPanel(new GridBagLayout());
    GridBagConstraints gbc = new GridBagConstraints();
    gbc.fill = GridBagConstraints.BOTH;
    gbc.weightx = 1;
    gbc.weighty = 1;
    gbc.gridheight = 4;
    gbc.gridwidth = 4;
    gbc.gridx = 0;
    gbc.gridy = 0;
    JPanel panelOne = new JPanel();
    //add some content
    mainPanel.add(panelOne, gbc);

    gbc.gridheight = 3;
    gbc.gridwidth = 1;
    gbc.gridx = 4;
    gbc.gridy = 0;
    JPanel panelTwo = new JPanel();
    //Add some content
    mainPanel.add(panelTwo, gbc);

    gbc.gridheight = 1;
    gbc.gridwidth = 4;
    gbc.gridx = 0;
    gbc.gridy = 4;
    JPanel panelThree = new JPanel();
    //Add some content
    mainPanel.add(panelThree, gbc);

    gbc.gridheight = 2;
    gbc.gridwidth = 1;
    gbc.gridx = 4;
    gbc.gridy = 3;
    JPanel panelFour = new JPanel();
    //Add some content
    mainPanel.add(panelFour, gbc);

    mainFrame.setContentPane(mainPanel);

さまざまなパラメーターを使用して何度も試行し、weightx と weighty を追加/削除しましたが、成功しませんでした。

ここにバリアントがあります。コピー＆ペーストするだけです：
