java - 无法在 Swing 中水平显示 2 个 JTable

Question

我需要沿 x 轴显示 2 个 JTable。我能够垂直显示它们(Y 轴)。这是我目前所做的:

但我想显示如下表格，

这是我的代码:

    tableA = new JTable(data, colNames);
    tableB = new JTable(data, colNames);

    JLabel labelA = new JLabel("Table-A");
    JLabel labelB = new JLabel("Table-B");

    JButton bt_copy = new JButton("Copy");

    Container c = frame.getContentPane();

    c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS));

    c.add(labelA);
    c.add(tableA.getTableHeader());
    c.add(tableA);

    c.add(labelB);
    c.add(tableB.getTableHeader());
    c.add(tableB);

    c.add(bt_copy);

当我将 c.setLayout(new BoxLayout(c, BoxLayout.Y_AXIS)); 中的 Y 轴更改为 X 轴 .我的 GUI View 真的很糟糕。

是这样的吗？？

JTable leftTable = new JTable();
JTable rightTable = new JTable();

addButton = new JButton("Add >>");
removeButton = new JButton("<< Remove");

setLayout(new GridBagLayout());

// Prepare the buttons panel...
JPanel pnlActions = new JPanel(new GridBagLayout());
pnlActions.setBorder(new LineBorder(Color.RED));
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 1;
gbc.anchor = GridBagConstraints.SOUTH;
gbc.weighty = 1;
gbc.fill = GridBagConstraints.HORIZONTAL;
pnlActions.add(addButton, gbc);
gbc.weighty = 0;
gbc.gridy++;
pnlActions.add(removeButton, gbc);

// Prepare the main layout
gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.weightx = 0.33;
gbc.fill = GridBagConstraints.BOTH;
gbc.weighty = 1;

add(new JScrollPane(leftTable), gbc);
gbc.gridx = 2;
add(new JScrollPane(rightTable), gbc);

gbc.gridx = 1;
gbc.gridy++;
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.weighty = 0;
add(pnlActions, gbc);
