如何在 jscrollpane 中设置表格以及如何显示表格 header

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。 Table header 不显示。如何设置 table.I 的大小已使用 Google 但代码无法工作

Answer 1

要显示 table header，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));
