iTextSharp 5.4.2 : Fixing the width of a column in a table

I am using following code to generate PDF doc using iTextSharp library version 5.4.2. 

// Create a Document object
        var document = new Document(PageSize.A4, 50, 50, 25, 25);

        // Create a new PdfWriter object, specifying the output stream
        var output = new MemoryStream();
        var writer = PdfWriter.GetInstance(document, output);

        // Open the Document for writing
        document.Open();



    //Gets System.Web.UI.WebControls.Table
    //Returns HTML table with 4 coulms

        var flowsheetTable = GetTable(report);


        var stringWriter = new StringWriter();
        using (var htmlWriter = new HtmlTextWriter(stringWriter))
        {
            flowsheetTable.RenderControl(htmlWriter);
        }


        List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(stringWriter.ToString()), null);
        for (int k = 0; k < htmlarraylist.Count; k++)
        {
            document.Add((IElement)htmlarraylist[k]);
        }


        document.Close();

        Response.ContentType = "application/pdf";
        Response.AddHeader("Content-Disposition", "attachment;filename=Receipt-test.pdf");
        Response.BinaryWrite(output.ToArray());

The method GetTable() returns a System.Web.UI.WebControls.Table which is having 4 columns. Is there any way to fix the width of first column in the table. I want first column to take 40% of total width.

Thank you

While you're looping through the collection of IElement objects you can individual cast, inspect and modify each one. In your case you might want to do something like this:

//Sample table with four columns
var sampleTable = "<table><tr><td>A</td><td>B</td><td>C</td><td>D</td></tr></table>";

//Parse sample HTML to collection if IElement objects
List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(sampleTable), null);

//Declare variables for use below
IElement ele;
PdfPTable t;

//Loop through the collection
for (int k = 0; k < htmlarraylist.Count; k++) {

    //Get the individual item (no cast should be needed)
    ele = htmlarraylist[k];

    //If the item is a PdfPTable
    if (ele is PdfPTable) {

        //Get and cast it
        t = ele as PdfPTable;

        //Set the widths (40%/20%/20%/20%)
        t.SetWidths(new float[] { 4, 2, 2, 2 });

    }

    //Regardless of what was done above, add the object to our document
    document.Add(ele);
}
