用iTextSharp生成PDF文档，其实很简单
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
