ITextsharp PDF Writer无法正确显示HTML

Question

我正在使用ITextSharp生成PDF，我在pdf文档中生成HTML表格，但它在PDF文件中无法正确显示。我复制了生成的HTML并签入了HTML文件，它在HTML文件中正确显示

这是HTML文件中的HTML

这是我的PDF文件

这是我的代码

 var data = MyClass.GetHistory();//It returns a Data Table
            var stream = new MemoryStream();
            Document document = new Document(PageSize.A4, 50, 50, 25, 25);
            PdfWriter writer = PdfWriter.GetInstance(document, stream);
            document.Open();

StringBuilder sb = new StringBuilder();
                sb.Append("<table style=\"border-collapse: collapse;  border-spacing: 0;  width: 100%;  margin-bottom: 15px;  border: 1px solid #dddddd; font-family: Arial, Helvetica, sans-serif; font-size:14px\">");
                sb.Append("<thead>");
                sb.Append("<tr>" + title + "</tr");
                sb.Append("<tr>");
                sb.Append(" <th style=\"padding: 8px;  line-height: 1.428571429;  vertical-align: top;  border-top: 1px solid #dddddd;  border: 1px solid #dddddd; border-bottom: 2px solid #dddddd;  background:#DCEBFD; text-align:left;\">Date</th>");
                sb.Append(" <th style=\"padding: 8px;  line-height: 1.428571429;  vertical-align: top;  border-top: 1px solid #dddddd;  border: 1px solid #dddddd; border-bottom: 2px solid #dddddd;  background:#DCEBFD; text-align:left;\">Description</th>");
                sb.Append(" <th style=\"padding: 8px;  line-height: 1.428571429;  vertical-align: top;  border-top: 1px solid #dddddd;  border: 1px solid #dddddd; border-bottom: 2px solid #dddddd;  background:#DCEBFD; text-align:left;\">City</th>");
                sb.Append(" <th style=\"padding: 8px;  line-height: 1.428571429;  vertical-align: top;  border-top: 1px solid #dddddd;  border: 1px solid #dddddd; border-bottom: 2px solid #dddddd;  background:#DCEBFD; text-align:left;\">State</th>");
                sb.Append(" </tr>");
                sb.Append(" </thead>");
                sb.Append(" <tbody>");

                foreach (var rows in data.Rows)
                {
                    sb.Append("<tr>");
                    foreach (var item in ((System.Data.DataRow)(rows)).ItemArray)
                    {
                        sb.Append("<td style=\"padding: 8px;  line-height: 1.428571429;  vertical-align: top;  border-top: 1px solid #dddddd;  border: 1px solid #dddddd; width: 125px\">" + item + "</td>");
                    }
                    sb.Append("</tr>");
                }

                //sb.Append("<td>1</td><td>2</td><td>3</td><td>4</td><td>5</td>");

                //sb.Append(" <tr><td>This is a test</td><td>2/td><td>3</td><td>4</td><td>5</td><tr/>");
                //sb.Append(" <tr><td>This is a test</td><td>This is a test</td><td>This is a test</td><td>This is a test</td><td>This is a test</td><tr/>");
                sb.Append(" </tbody>");
                sb.Append(" </table>");

其次我想从日期只显示年份和月份，如果当前项目是日期时间，我如何检查foreach循环内部？

我建议你在这种情况下使用iTextSharp.text.pdf.PdfPTable对象。 html表似乎更简单，您可以使用iTextSharp.text.pdf.PdfPTable更快地完成您的需求。
