NPOI已出现一段时间了，目前版本2.0 Beta 2 [v2.0.5]，网上关于NPOI操作xlsx文章较多，而关于docx的几乎没有，尽管NPOI对于Word还不稳定，经过一阵捣鼓后终于实现了表的简单操作：创建表、创建行、创建单元，单元行和列的合并。

        环境：vs2010,netframework4

 NPOI：由于目前网上提供的NPOI对于Word还不稳定，上述代码不能保证能用。

 经过调试的例子下载：http://download.csdn.net/detail/gltide/6753163，例中附有最新NPOI。

最新NPOI（2.0RC）及上述例子（2014-1-9）：http://download.csdn.net/detail/gltide/6829979，例中增加对页面设置和表居中代码。
