If you are trying too export your repeater data to PDF in table structure then you can use the below code i think it will help you out.
this code will align your data in table structure in Left-bottom manner of each table cell.
Document myDocument = new Document(PageSize.A4);
PdfWriter myPdfWriter = PdfWriter.GetInstance(myDocument, new FileStream(strPDFFilePath, FileMode.Create));
myDocument.Open();
myDocument.NewPage();
PdfContentByte myPdfContentByte = myPdfWriter.DirectContent;
PdfPCell myCell; Paragraph myParagraph;
PdfPTable myTable = new PdfPTable(4);
myTable.WidthPercentage = 100;
myTable.SetWidths(new int[4] { 25, 25, 25, 25 });
myTable.DefaultCell.BorderWidth = 1;
myTable.DefaultCell.BorderColor = BaseColor.RED;
for (int i = -100; i < 100; i++)
{
myParagraph = new Paragraph(String.Format("Alignment: {0}", i)); myParagraph.Font.SetFamily("Verdana");
myParagraph.Font.SetColor(72, 72, 72);
myParagraph.Font.Size = 11;
myCell = new PdfPCell();
myCell.AddElement(myParagraph);
myCell.HorizontalAlignment = i;
myCell.VerticalAlignment = i;
myTable.AddCell(myCell);
}
myDocument.Add(myTable);
myDocument.Add(new Chunk(String.Empty)); }
myDocument.Close();
