java如何在滚动窗格中设置选项卡以及如何显示选项卡标题

Question

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class StatusPage extends JPanel
{
    DefaultTableModel dm;
    JTable table;
    JScrollPane jsb;

    public StatusPage()
    {
        String col_name[] = {"S.No.","Book Name","Author Name","Available Book","Issue Book","Total Book"};
        String data[][] = {{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"},{"1","Vikash","All","A","All","A"}};

        dm = new DefaultTableModel(data,col_name);
        table = new JTable(dm);
        jsb = new JScrollPane(table);
        add(table);
    }
}

请检查错误。表格标题不显示。如何设置表的大小。我用过谷歌，但代码不能工作

Answer 1

要显示表格标题，您应该在面板或框架中添加JScrollPane，而不是table

所以你应该这样做：

add(new JScrollPane(table));
