![表格数据]()
表格可以自己加入数据
通过代码解析 得到集合类
再通过前台进行获取
我这里将包导出成jar 放到WebRoot/WEB-INF/lib目录下
最后附上页面代码
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%@page import="com.jx.*"%><%
jx j = new jx();
List<List<Object>> list = null;
List<Object> mlist = null;
List<List<Object>> hlist = null;
hlist=j.Test(list, mlist);
%><%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head></head><body>
<table border="1" cellspacing="2" cellpadding="1" align="center"
width="80%">
<% for (int i = 0; i < j.count; i++) {
%>
<tr>
<% for (int k = 0; k < j.row1; k++) {
%>
<td><%=hlist.get(i).get(k)%></td>
<%
}
%>
</tr>
<%
}
%>
</table></body></html>
实现的方式很多，不推荐在页面中直接放小脚本
