Add Footer to a pdf using iTextSharp C#

Question

The code below saves a 1 page pdf
How do I add a footer to it?

table.AddCell(PhraseCell(new Phrase("Name:", FontFactory.GetFont("Arial", 8, iTextSharp.text.Font.BOLD, BaseColor.BLACK)), PdfPCell.ALIGN_LEFT));
 phrase = new Phrase(new Chunk(sName + "\n\n", FontFactory.GetFont("Arial", 8, iTextSharp.text.Font.NORMAL, BaseColor.BLACK)));
 table.AddCell(PhraseCell(phrase, PdfPCell.ALIGN_LEFT));
 cell = PhraseCell(new Phrase(), PdfPCell.ALIGN_CENTER);
 cell.Colspan = 2;
 cell.PaddingBottom = 10f;
 table.AddCell(cell);

 document.Add(table);
 document.Close();

byte[] bytes = memoryStream.ToArray();
string uncPath1 = @"\\MyServer\MyFolder$\temp\";
File.WriteAllBytes(SharedPath + "employee.pdf", bytes);

Never mind!
I've fixed it using the code below:

PdfPTable tbfooter = new PdfPTable(3);
                tbfooter.TotalWidth = document.PageSize.Width - document.LeftMargin - document.RightMargin;
                tbfooter.DefaultCell.Border = 0;
                tbfooter.AddCell(new Paragraph());
                tbfooter.AddCell(new Paragraph());
                var _cell2 = new PdfPCell(new Paragraph(new Chunk("This is my Footer...", FontFactory.GetFont("Arial", 8, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLUE))));
                _cell2.HorizontalAlignment = Element.ALIGN_RIGHT;
                _cell2.Border = 0;
                tbfooter.AddCell(_cell2);
                tbfooter.AddCell(new Paragraph());
                tbfooter.AddCell(new Paragraph());
                var _celly = new PdfPCell(new Paragraph(writer.PageNumber.ToString()));//For page no.
                _celly.HorizontalAlignment = Element.ALIGN_RIGHT;
                _celly.Border = 0;
                tbfooter.AddCell(_celly);
                float[] widths1 = new float[] { 20f, 20f, 60f };
                tbfooter.SetWidths(widths1);
                tbfooter.WriteSelectedRows(0, -1, document.LeftMargin, writer.PageSize.GetBottom(document.BottomMargin), writer.DirectContent);
