ITextSharp 4.1.6. PDF Table - how to remove whites

问题:

I'm having a problem with ITextSharp's tables. I'd like to have cells without top & bottom padding, so that they are placed closer to each other.

Although I have set the padding and the leading of the cell to 0, the white-space still remains.

Does anyone please know how to remove the whitespace ?

EDIT:

Thanx to prompt answer from Dylan, I've managed to resolve my issue. Here's the source snippet if someone gets across similar issue

        Document document = new Document(PageSize.A4, 5, 5, 10, 10);
        using (FileStream fs = new FileStream("C:\\Users\\brum\\Desktop\\untitled.pdf", FileMode.Create))
        {
            iTextSharp.text.pdf.PdfWriter.GetInstance(document, fs);
            document.Open();
            PdfPTable table = new PdfPTable(2);
            PdfPCell cell = new PdfPCell(new Phrase("Spanning 2 cols"));

            cell.Colspan = 2;
            cell.HorizontalAlignment = 1;
            cell.Padding = 0f;
            cell.UseAscender = true;
            table.AddCell(cell);

            table.AddCell("Next row 1");
            table.AddCell("Next row 2");

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

cell.UseAscender = true; // This is the line that did the trick for me

回答1:

Set the top padding to something small or even negative. Another option is PdfPCell.setUseAscender().

ex:

cell.setPaddingTop(0f);  // No padding on top cell

or

cell.UseAscender = true;

Please paste the code you have.
