Java 在miglayou中调整表的大小

我创建了一个MigLayout，如下所示：

public JScrollPane createLayout() {
    JPanel panel = new JPanel(new MigLayout("debug 400"));
    JScrollPane sp;

    JLabel lab = new JLabel(labelValue);
    lab.setFont(new Font("Tahoma", Font.BOLD, 15));

    panel.add(lab, "wrap");
    panel.add(resultsTable(), "growx, wrap");
    panel.add(resultsButtons(), "wrap");

    //set table properties
    tableProperties(resultTable);
    updateResultsTable();

    sp = new JScrollPane(panel);
    sp.repaint();
    sp.validate();

    return sp;
}

private JPanel resultsTable() {
    JPanel panel = new JPanel(new MigLayout(""));
    JScrollPane scrollTablePane;
    rtm = new ResultTableModel(resultList);
    resultTable = new JTable(rtm);
    scrollTablePane = new JScrollPane(resultTable);
    sorter = new TableRowSorter<TableModel>(resultTable.getModel());
    resultTable.setRowSorter(sorter);

    scrollTablePane.repaint();
    scrollTablePane.validate();

    //add to panel
    panel.add(scrollTablePane);
    panel.repaint();
    panel.validate();

    return panel;
}

如您所见，该表的大小调整不正确

我正在创建这样的布局：

public JScrollPane createLayout() {
    JPanel panel = new JPanel(new MigLayout("debug 400"));
    JScrollPane sp;

    JLabel lab = new JLabel(labelValue);
    lab.setFont(new Font("Tahoma", Font.BOLD, 15));

    panel.add(lab, "wrap");
    panel.add(resultsTable(), "growx, wrap");
    panel.add(resultsButtons(), "wrap");

    //set table properties
    tableProperties(resultTable);
    updateResultsTable();

    sp = new JScrollPane(panel);
    sp.repaint();
    sp.validate();

    return sp;
}

private JPanel resultsTable() {
    JPanel panel = new JPanel(new MigLayout(""));
    JScrollPane scrollTablePane;
    rtm = new ResultTableModel(resultList);
    resultTable = new JTable(rtm);
    scrollTablePane = new JScrollPane(resultTable);
    sorter = new TableRowSorter<TableModel>(resultTable.getModel());
    resultTable.setRowSorter(sorter);

    scrollTablePane.repaint();
    scrollTablePane.validate();

    //add to panel
    panel.add(scrollTablePane);
    panel.repaint();
    panel.validate();

    return panel;
}

我的表是这样创建的：

public JScrollPane createLayout() {
    JPanel panel = new JPanel(new MigLayout("debug 400"));
    JScrollPane sp;

    JLabel lab = new JLabel(labelValue);
    lab.setFont(new Font("Tahoma", Font.BOLD, 15));

    panel.add(lab, "wrap");
    panel.add(resultsTable(), "growx, wrap");
    panel.add(resultsButtons(), "wrap");

    //set table properties
    tableProperties(resultTable);
    updateResultsTable();

    sp = new JScrollPane(panel);
    sp.repaint();
    sp.validate();

    return sp;
}

private JPanel resultsTable() {
    JPanel panel = new JPanel(new MigLayout(""));
    JScrollPane scrollTablePane;
    rtm = new ResultTableModel(resultList);
    resultTable = new JTable(rtm);
    scrollTablePane = new JScrollPane(resultTable);
    sorter = new TableRowSorter<TableModel>(resultTable.getModel());
    resultTable.setRowSorter(sorter);

    scrollTablePane.repaint();
    scrollTablePane.validate();

    //add to panel
    panel.add(scrollTablePane);
    panel.repaint();
    panel.validate();

    return panel;
}

有什么建议可以解释为什么我的表中的列不拉伸

谢谢你的回答

如果您希望表格能够自动调整大小，请尝试在

createLayout

方法中使用以下构造函数

JPanel panel=new JPanel（new migloayout（“debug 400，wrap 1”），“[grow，fill]”，“[grow，fill]”，

和在

resultsTable

方法中使用以下构造函数

JPanel panel panel=new JPanel（new migloayout（“，”[grow，fill]，“[grow，fill]”）查看此相关问答：。我在您的代码中遇到了一些缺少的标识符：resultsButtons（）、resultable、updateResultsTable（）、rtm、类resultableModel[来自NCSA、gSwing、DFKI？]、resultList和sorter。是否使用？
