帮忙看看错漏/(ㄒoㄒ)/~~JTtable结合滚动面板显示数据

[YKW_]

期末的课程设计任务，实现一个酒店管理系统 现在想用Ttable结合滚动面板显示数据库存放的房间信息数据，数据库数据的导出操作正常，就是无法显示 我是用vector来存放列名和接收各行数据 昨晚弄到现在死活显示不了 不知道问题在哪 大家指点一下 不胜感激啊 /(ㄒoㄒ)/~~/(ㄒoㄒ)/~~

来人啊来人啊

[qidongting]

JTable table= new JTable(dt); JScrollPane scrollPane=new JScrollPane(table); System.out.println(v_sum); table.setModel(dt); table.updateUI(); 你貌似没有将scrollPane放入任何一个面板上啊，那表格当然显示不出来啊！

[YKW_]

DefaultTableModel dt = new DefaultTableModel(); dt.setDataVector(v_sum, v_title); JTable table= new JTable(dt); JScrollPane scrollPane=new JScrollPane(table); p4.add(scrollPane); System.out.println(v_sum); 哦哦 一时遗漏 但是我修改完的代码还是显示不出来数据啊 麻烦看看
