简单Table例子，就是不能正常显示表格及内容还报错！

Java code

import javax.swing.JFrame;
 import javax.swing.JScrollPane;
 import javax.swing.JTable;
 
 public class TableTest1 {
     public static void main(String[] args) {
         JFrame frame = new JFrame("Test Table");
 
         String[] titles = { "姓名", "年龄", "性别", "数学成绩", "英语成绩", "总分", "是否及格" };
 
         Object userInfo[][] = { { "李兴华", 30, "男", 100, 99, 199, true },
                 { "张三", 29, "女", 99, 88, false } };
 
         JTable table = new JTable(userInfo, titles);
         JScrollPane scr = new JScrollPane(table);
 
         frame.add(scr);
         frame.setSize(370, 90);
         frame.setVisible(true);
         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     }
 }

报错为

------解决方案--------------------
Object userInfo[][] = { { "李兴华", 30, "男", 100, 99, 199, true },
{ "张三", 29, "女", 99, 88, false } };
第二个变量少了一个参数。
Object userInfo[][] = { { "李兴华", 30, "男", 100, 99, 199, true },
{ "张三", 29, "女", 99, 88,187, false } };
