使用iTextSharp的Rowspan无法正常工作

Question

I'm trying to create a simple table with iTextSharp, so with C#. The goal is a table like this one:

The problem is that if I apply the rowspan as 2 on cell A, iTextSharp does not render the rowspanned cell, this means that the cell have the same height of cell B. Here's the code:

    PdfPTable corporateTable = new PdfPTable(2);
    corporateTable.HeaderRows = 1;
    corporateTable.TotalWidth = pdfWidth - 50;

    PdfPCell vCell = new PdfPCell();
    vCell.Border = Rectangle.BOX;
    vCell.Rowspan = 2;
    vCell.Phrase = new Phrase("A", new Font(fontLh, 7f, 1, BaseColor.BLACK));
    corporateTable.CompleteRow();
    corporateTable.AddCell(vCell);


    PdfPCell vCellx = new PdfPCell();
    vCellx.Phrase = new Phrase("B", new Font(fontLh, 7f, 1, BaseColor.BLACK));
    vCellx.Colspan = 3;
    corporateTable.AddCell(vCellx);

    PdfPCell vCell1 = new PdfPCell();
    vCell1.Phrase = new Phrase("C", new Font(fontValue, 7f, 0, BaseColor.BLACK));
    corporateTable.AddCell(vCell1);

    corporateTable.WriteSelectedRows(0, -1, 100f, 100f, writer.DirectContent);
    document.Close();

What's wrong? I'm using the latest version of the dll.

Answer 1

Well the basic answer is: it works! if you add two more cells, you will see that one cell (the one underneath A) is not filled.

But this is not what you expect (nor did I btw). To achive what you want use nested tables, that means:

• create a table with two cols
• insert cell A into table
• create cell 2
• create one more table with 1 col
  • insert cell B into table 2
  • insert cell c into table 2
• insert table 2 into cell 2

search for itext rowspan, you will find multiple fully typed out examples.

Answer 2

I think it will work. Try to remove following code rows:

corporateTable.CompleteRow();
...
vCellx.Colspan = 3;

Answer 3

The problem is at

vCellx.Colspan = 3; 

Use

vCellx.Colspan = 1; 

because you declared pdf table with two columns. You already added one column with rowspan 3 so you have only another one column and not three columns
