jtable 中不显示水平滚动条。如何使列停止收缩？

Question

我正在向我的 JTable 添加一个 JScrollPane HORIZONTAL_SCROLLBAR_AS_NEEDED 和 VERTICAL_SCROLLBAR_AS_NEEDED.
并设置 JTable.AUTO_RESIZE_OFF。但是当我添加一堆列时，列的名称没有正确显示，它们缩小以适应 table。水平滚动条不显示。

这里是代码和图片：

tableForDay1 = new JTable();
tableForDay1.setBounds(0, 619, 1337, -619);
tableForDay1.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
tableForDay1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

JScrollPane scrollBar1 = new JScrollPane (tableForDay1, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
scrollBar1.setVisible(true);
day1.setLayout(new BoxLayout(day1, BoxLayout.X_AXIS));
createColumns(tableForDay1);

这是我添加的列：（我将 table 作为参数传递）

private void createColumns(JTable table)
{
    //get table model
    DefaultTableModel tableModel = new DefaultTableModel();
    table.setModel(tableModel);
    tableModel.addColumn("אזור");
    tableModel.addColumn("מוביל");
    tableModel.addColumn("ת.ה");
    tableModel.addColumn("מ.ה");
    tableModel.addColumn("קוד מוצר");
    tableModel.addColumn("יישוב");
    tableModel.addColumn("שעת תאום");
    tableModel.addColumn("תוספות למוצר");
    tableModel.addColumn("כתובת");
    tableModel.addColumn("קומה");
    tableModel.addColumn("דירה");
    tableModel.addColumn("שם הלקוח");
    tableModel.addColumn("תאור מוצר");
    tableModel.addColumn("פלאפון");
    tableModel.addColumn("אישר קשר נוסף");
    tableModel.addColumn("פירוט מחיר");
    table.getTableHeader().setFont(new Font("Ariel", Font.BOLD, 27));

    String[]row = { "something", "something", "something", "something" , 
            "something" , "something" , "something" , "something", "something", 
            "something", "something" , "something" , "something" , "something" };

    tableModel.addRow(row);
}

图片如下：列名显示不正确，列未对齐

我该如何解决这个问题？

Answer 1

getColumnModel().getColumn(0).setPreferredWidth(*insert your width here*);

您必须为每个列执行此操作。
