itextsharp: default pdfptable filling

Question

if i define a table like this:

 Dim datatable As PdfPTable = New PdfPTable(4)

and i dont have 4 cells to add in it, how can i make it so that it automatically fills the cell if there are not enough cells?

i am finding that unless i have at least 4 cells in there, it wont display it

the question is how do i figure out which cells are blank?

Answer 1

How about filling with empty Cells?

Edit
Something like:

yourPdfPTable.AddCell(yourEmptyPdfPCell)

Where yourEmptyPdfPCell is a cell with an empty string.

Answer 2

Something like, figure out programmatically which cells are blank, and then for those cells:

iTextSharp.text.pdf.PdfPTable pt = new iTextSharp.text.pdf.PdfPTable(100);
iTextSharp.text.pdf.PdfPCell cBlank = new iTextSharp.text.pdf.PdfPCell(new Phrase(" "));
pt.AddCell(cBlank);
