این کد رو برای CustomHeader  م نوشتم :

var table = new PdfPTable(numColumns: 2) { WidthPercentage = 100 };

            table.AddSimpleRow((cellData, cellProperties) =>
            {
                cellData.Value = "باسمه تعالی " + "\r\n" + "حوزه علمیه امیر المومنین (ع) - معاونت آموزش - کارنامه تحصیلی طلبه";
                cellProperties.PdfFont = PdfRptFont;
                cellProperties.PdfFontStyle = DocumentFontStyle.Bold;
                cellProperties.HorizontalAlignment = HorizontalAlignment.Center;
                cellProperties.RunDirection = PdfRunDirection.RightToLeft;
            }, (cellData, cellProperties) =>
            {
                cellData.CellTemplate = new ImageFilePathField();
                cellData.Value = _imagePath;
                cellProperties.HorizontalAlignment = HorizontalAlignment.Right;
            });  
 

اولین مشکل اینه که متن هدر میاد سمت چپ در حالی که منHorizontalAlignment   رو برابر Center کردم ، دوم اینکه چجوری میتونم کادر مشخصات طلبه رو در پایین ایجاد کنم وقتی قبلش گفتم که numcolumns : 2 هست؟
