Java制作Excel模板
POI & EasyExcel
POI
Apache POI是Apache软件基金会的开源项目，POI提供API给Java程序对Microsoft Office格式档案读和写的功能。
.NET的开发人员则可以利用NPOI (POI for .NET) 来存取 Microsoft Office文档的功能。
EasyExcel
EasyExcel是一个基于Java的简单、省内存的读写Excel的开源项目。
在尽可能节约内存的情况下支持读写百M的Excel。
EasyExcel是阿里的开源项目，使用起来简单方便快捷舒适且优雅，但是功能有限。
使用POI绘制表格
在第一次开发项目中遇到需要批量导出Excel，此时有两个选择：导入Excel填数据和手绘Excel。第一种方法用EasyExcel就可以很方便实现，但是第二种方法只有用POI
（主要是EasyExcel真不会o(╥﹏╥)o）
