How to create Table inside Table using iTextSharp in ASP.Net

I have a pdfptable like this

pdfptable tbl =new pdfptable(2);
pdfpcel celll=new pdfpcell();



tbl.addcell(cell);//First table added

before we added the second table i want to create a table inside second table

pdfptable innerttbl =new pdfptable(2);
pdfpcel innercelll=new pdfpcell();

innerttbl .addcell(innercelll);
innerttbl .addcell(innercelll);

dcoument.add(innertable);//inner table added
cell.addelement(innertable);

document.add(table)

Is This Possible in Itextsharp in asp.net
