iTextSharp need to repeat table rows with textfield dynamically

问题

I am reading and filling a dynamic pdf template(having dynamic table with textfields in each cell) below way using iTextSharp [assuming I would be getting a single product info from source]:

FileStream fs = new FileStream("C:\\ABC\\DestinationFile.pdf", FileMode.Create);

PdfReader reader = new PdfReader("C:\\ABC\\SourceTemplateFile.pdf");
PdfStamper stamper = new PdfStamper(reader, fs);
xfa = stamper.AcroFields.Xfa;

string[] strProductList = productInfo.Product.Split('|');
string dName= string.Format("{0} {1}", strProductList[0], strProductList[1]);
string labeling = string.Format("{0} {1}/{2}", strProductList[4], strProductList[2], strProductList[3]);
string dID = strProductList[5];
xfa.SetNodeText(xfa.FindDatasetsNode("TextField1"), dID);
xfa.SetNodeText(xfa.FindDatasetsNode("TextField2"), dName);
xfa.SetNodeText(xfa.FindDatasetsNode("TextField3"), labeling);

TemplateFile:

And XFA XML is:

But in certain cases I would be getting multiple product info from source. So, I need to repeat the rows dynamically to fill the form in "SourceTemplateFile.pdf"

Multiple row filling code:

FileStream fs = new FileStream("C:\\ABC\\DestinationFile.pdf", FileMode.Create);

        PdfReader reader = new PdfReader("C:\\ABC\\SourceTemplateFile.pdf");
        PdfStamper stamper = new PdfStamper(reader, fs);
        xfa = stamper.AcroFields.Xfa;

        int i = 1;
        foreach (ProductInfo n in iwbProds)
        {

            string[] strProductList = n.Product.Split('|');
            string dName= string.Format("{0} {1}", strProductList[0], strProductList[1]);
            string labeling = string.Format("{0} {1}/{2}", strProductList[4], strProductList[2], strProductList[3]);
            string dID = strProductList[5];
            xfa.SetNodeText(xfa.FindDatasetsNode(string.Format("TextField{0}", i++)), dID);
            xfa.SetNodeText(xfa.FindDatasetsNode(string.Format("TextField{0}", i++)), dName);
            xfa.SetNodeText(xfa.FindDatasetsNode(string.Format("TextField{0}", i++)), labeling);
        }

So, my question is how to repeat the rows dynamically in a given pdf temple? If I would get 3 product info from source then there should be 3 rows available to fill. Or Is dynamic pdf form filling supported by iTextSharp?
