我已經創建了用於從HTML文件準備PDF的代碼。我的問題是生成的PDF不顯示我的HTML表格的邊框。我沒有使用任何CSS文件，所有的豎框都是內聯寫入的。以下是我的HTML示例。顯示頁眉/頁腳和HTML表格網格線[使用iTextSharp生成HTML到PDF]
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<table cellpadding="0" cellspacing="0" border="0" width="100%" style=" font-family:'Times New Roman', Times, serif; font-size:12px; margin:20px 0px; border:10px solid #000; color:#000;">
<tr>
<td width="40%" align="center"><img src="[LOGOIMAGE]" alt="logo" /></td>
<td width="30%" align="center" style="border-left:1px solid #000;">June, 26 2013<br />page 1 of 3</td>
<td width="30%" align="center" style="border-left:1px solid #000;">123456<br />Name</td>
</tr>
</table>
</body>
</html>
我也嘗試增加邊框寬度高達10px的，因爲谷歌搜索時我發現，一些其他開發商也面臨同樣的問題，嘗試這種解決它，但是這並沒有爲我工作。
我正在使用下面的代碼來生成PDF。
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Details.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
// Document d = new Document(new Rectangle(100f, 300f));
var doc = new Document(PageSize.A4, 50, 50, 25, 25);
// Create a new PdfWriter object, specifying the output stream
var output = new MemoryStream();
// var writer = PdfWriter.GetInstance(doc, output);
string path = Server.MapPath("pdfs");
PdfWriter.GetInstance(doc, new FileStream(path + "/doc3.pdf", FileMode.Create));
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
string contents = File.ReadAllText(Server.MapPath("myfile.html"));
contents = contents.Replace("[LOGOIMAGE]", Server.MapPath("App_Data/images/logo.jpg"));
var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), null);
// Enumerate the elements, adding each one to the Document...
foreach (var htmlElement in parsedHtmlElements)
doc.Add(htmlElement as IElement);
doc.Close();
Response.Write(doc);
Response.End();
