Asp.Net 常用工具类之Office-文档操作（6）

　　　　文档一直是老大难问题，君不知，代码用时方恨少！有一套成熟的文件帮助类能很大程度上减少寻找各种资料的时间。

　　　　记得以前做一个业务，需要导出协议，一份可编辑，一份不可编辑。那么Word和PDF是最好的选择，Word可编辑，PDF只给客户方面看！

　　　　前两天复习了一下Excel的操作，主要运用到NPOI组件。

　　　　今天给大家带来的是另一个组件Spire.DataExport的使用，主要是进行HTML，Word，PDF的导出操作。

　　　　第一次用到Spire.DataExport还是去年上半年的时候。说实话，非常强大，特别是针对于文档的转换和导入导出操作，非常便利，且使用简单,大家有兴趣的可以去官网查看相关资料，Demo非常清晰明了。

　　　　DataTable转Word
