Java poi导出LuckySheet在线表格
章丰茂
目前已经实现部分基于POI从零解析导出。（字体、边框、图片、数据验证（部分）、行列冻结、样式）
Java后台地址代码 ：https://gitee.com/zzq100/luckysheet-demo
1.为啥使用Luckysheet？
Luckysheet（https://github.com/mengshukeji/Luckysheet）是一款轻量的在线Excel渲染框架，易集成使用。支持二次开发，最重要的是渲染真的很快、开源免费的！！！
2.Luckysheet目前使用
目前luckysheet虽然在渲染上很不错，但是毕竟是刚刚开源，使用上会有一些小BUG。关于导入导出官方有给出demo：https://github.com/mengshukeji/Luckyexcel
话不多说上干货
将官方的代码拉取下来自己创建一个页面 下载地址–>官方链接
布局代码如下，可以直接复制下来。但是注意下上传下载数据，只是个例子，需要自己修改。上传必须用post哦，因为数据太大了！
