python操作word文档（python-docx）
写这篇博客源于博友的提问，将介绍如何使用python-docx操作word文档。python-docx不支持表格内文本水平居中，可以考虑使用itextpdf，生成pdf的表格然后在转回word。
itexpdf7支持的样式都比较灵活和多样。
1. 效果图
1. 1 python-docx效果图
先使用55表格，然后在行中分别对某些cell在添加一个小的12的table实现
直接用5*9表格，标头部分列cell进行合并，效果图如下：
python-docx不够灵活，没法居中等；但自带了比较多的样式：
Light Shading如下：
Light List样式如下：
Light Grid如下：
Medium Shading如下：
Medium List如下：
Dark List效果图如下：
Colorful Shading效果图如下：

2. 安装
前提依赖：
- Python 2.6, 2.7, 3.3, or 3.4
- lxml >= 2.3.2
pip安装python-docx：
pip install python-docx
3. 源代码
