Answer 1

You are adding the Image object directly to a PdfPCell like this:

iTextSharp.text.Image image128 = code128.CreateImageWithBarcode(cb, null, null);
BarCodeTable.AddCell(image128);

The second line is a short cut for something that looks like this:

PdfPCell cell = new PdfPCell();
cell.SetImage(image128);
BarCodeTable.AddCEll(cell);

This cell contains nothing more than an image. There is no room for text.

If you want to combine an image and text, you need something like this:

PdfPCell cell = new PdfPCell();
cell.AddElement(image128);
Paragraph p = new Paragraph("Student name");
p.Alignment = Element.ALIGN_CENTER;
cell.AddElement(p);
BarCodeTable.AddCEll(cell);
