Unable to vertically align text in table cell with itextsharp

Question

I can not figure out how to vertically align text in table cell. horizontal alignment is ok. I use itextsharp to generate pdf. Alignment should be applied to cells in table kitosKalbosTable. Any help would be appreciated. here's my code:

    var table = new PdfPTable(new float[]
                                  {
                                      36, 1, 63
                                  });
    table.WidthPercentage = 100.0f;
    table.HorizontalAlignment = Element.ALIGN_LEFT;
    table.DefaultCell.Border = Rectangle.NO_BORDER;
    table.SplitRows = false;
    .........
    PdfPTable kitosKalbosTable = new PdfPTable(new float[] {10, 30});
        kitosKalbosTable.TotalWidth = 40f;
        kitosKalbosTable.SplitRows = false;

        kitosKalbosTable.AddCell("Kalba", FontType.SmallTimes, vAligment: Element.ALIGN_MIDDLE, hAligment: Element.ALIGN_CENTER);
    ..........
    table.AddCell(kitosKalbosTable);

    //method in other file
    public static PdfPCell CreateCell(
    string text,
    FontType? fontType = FontType.RegularTimes,
    int? rotation = null,
    int? colspan = null,
    int? rowspan = null,
    int? hAligment = null,
    int? vAligment = null,
    int? height = null,
    int? border = null,
    int[] disableBorders = null,
    int? paddinLeft = null,
    int? paddingRight = null,
    bool? splitLate = null)
{
    var cell = new PdfPCell();
    ............

    if (vAligment.HasValue)
    {
        cell.VerticalAlignment = vAligment.Value;
    }

    return cell;
}

You have a complex example that appears to be using nested tables and extension methods. As Alexis pointed out, the VerticalAlignment is the correct property to use. Below is a full working example of this. I recommend getting rid of your extension method for now and just starting with this example.

//Our test file to output
var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "test.pdf");

//Standard PDF setup, nothing special here
using (var fs = new FileStream(testFile, FileMode.Create, FileAccess.Write, FileShare.None)) {
    using (var doc = new Document()) {
        using (var writer = PdfWriter.GetInstance(doc, fs)) {
            doc.Open();

            //Create our outer table with two columns
            var outerTable = new PdfPTable(2);

            //Create our inner table with just a single column
            var innerTable = new PdfPTable(1);

            //Add a middle-align cell to the new table
            var innerTableCell = new PdfPCell(new Phrase("Inner"));
            innerTableCell.VerticalAlignment = Element.ALIGN_MIDDLE;
            innerTable.AddCell(innerTableCell);

            //Add the inner table to the outer table
            outerTable.AddCell(innerTable);

            //Create and add a vertically longer second cell to the outer table
            var outerTableCell = new PdfPCell(new Phrase("Hello\nWorld\nHello\nWorld"));
            outerTable.AddCell(outerTableCell);

            //Add the table to the document
            doc.Add(outerTable);

            doc.Close();
        }
    }
}

Use

cell.VerticalAlignment = Element.ALIGN_MIDDLE; // or ALIGN_TOP or ALIGN_BOTTOM

Also, you can set a default vertical alignment for all cells by setting

kitosKalbosTable.DefaultCell.VerticalAlignment
