Java GUI 使用 Vector 类 建立表格

区别：之前是直接

String column = {"姓名","年龄","性别"};---表头

String content ={{"张三","58","男"}，{"李四","56","男"}，{"王五","12","女"}};---内容

JTable jtable = new JTable(content,column );

之后是：

将每个人的每个属性存到Vector的数组中，将数组放到表格中，（将表格放到JScrollPane中），将JScrollPane放到内容窗格上。

PS：不能直接将表格放到内容窗格上，因为无法显示表头（原因：我不知道）
