最近由于项目需要，在研究PDF文档的生成，发现用iTextSharp生成PDF文档时非常简单的一件事情；

之前在博客园中发现不少人都写了这方面的文章（http://www.cnblogs.com/islands/archive/2008/06/27/1231288.html），但是对于最新的版本没有更新，大部分代码是copy示例中的，导致我机器上没有办法运行，也许是版本问题吧，下面是我根据实际情况编写的代码，包含如下：

1、段落

2、表格

3、字体格式化

运行此代码需要的类库：

itextsharp.dll,itext-hyph-xml.dll,iTextAsian.dll和ICSharpCode.SharpZipLib.dll

itextsharp项目地址：http://sourceforge.net/projects/itextsharp/

示例代码,/Files/hudonglin/PDFMake.rar示例代码也贴在下面了

本代码支持中文字符，下面直接上代码
