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
