利用itextsharp导出pdf

在项目中，客户要求把一些表格导出pdf格式，在网上找了好久终于发现一个完美的解决方案，利用itextsharp可以很方便的导出pdf文件，不说太多了，直接上图，有图有真相

首先是页面图片



然后是导出的pdf图片



导出pdf代码如下：

//导出Mold pdf文档

public void exportpdf_Mold(string quotenum, string fullpath)

{

string pdfName = quotenum + ".pdf";

string savePath = "ExcelTemplate/" + pdfName;

//利用iTextSharp导出pdf

Rectangle rec = new Rectangle(792, 612);

Document document = new Document(rec);

document.SetMargins(18f, 18f, 36f, 36f);

PdfWriter pdfwriter = PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath(savePath), FileMode.Create));

document.Open();

PdfPTable pdftable = new PdfPTable(10);

pdftable.HorizontalAlignment = 1;

float[] cellwidth = { 5f, 4.5f, 3f, 3.5f, 2.5f, 2.6f, 2.5f, 2.5f, 2.5f, 2.8f };

pdftable.SetWidths(cellwidth);

//从数据库中读取tooling cost数据

string strSql = "select * from tooling_cost where quotenum='" + quotenum.Substring(2) + "' order by id asc";

DataTable dt_tooling = CommonMySql.MySql_Select(strSql);

strSql = "select * from part_cost where quotenum='" + quotenum.Substring(2) + "' order by id asc";

DataTable dt_part = CommonMySql.MySql_Select(strSql);

int newfamily = 0; //记录是否是新的familymold

int oldfamily = 0; //记录是否是老的familymold

//添加表头
