Creating a three column table in a pdf

The coding below reads data from a mySQL database, creates a pdf with a table in it and inserts the data into it.
I would like to modify it so that the table has three columns and each record from the query is inserted in the table, suitable for printing mailing labels. I realise that the SELECT statement would have to be changed to  create all the name and address fields. e.g:

Name1                                Name2                                     Name3
Address11                         Address21                              Address31
Address12                         Address22                              Address32

Name4                                .........
Address41
Address42

You should just have to construct the table, passing 3 as the number of columns required.
Change your widths array accordingly, and the colspan of the header row
Then just loop through the results as before:
using (MySqlDataReader reader = comm.ExecuteReader()) {
  while (reader.Read()) {
    string text = string.Format(
      "{0}\r\n{1}\r\n{2}\r\n{3}",
      reader["Name"],
      reader["Address1"],
      reader["Town"],
      reader["Postcode"]);
  
    table.AddCell(text);
  }
}

Thanks. Works fine now except for the top, bottom and side margins.
Assume I just juggle with TotalWidth, SpacingBefore, and SpacingAfter to adjust this.
I am hoping that the pdf produced will print with roughly the same spacing and layout on most printers and the text will fit on the labels. I suppose I could provide a dialog box to change the above parameters where the print is out of line with the labels.
Final coding is shown below.
Is there anything I should change in it? (apart from the username and password which I have changed!!!)

Document doc = new Document();
        PdfWriter.GetInstance(doc, new System.IO.FileStream("Test.pdf", System.IO.FileMode.Create));
        doc.Open();
        
        //PdfPTable table = new PdfPTable(2);
        PdfPTable table = new PdfPTable(3);
 
        //actual width of table in points
        //table.TotalWidth = 216f;
        table.TotalWidth = 550f;
        //fix the absolute width of the table
        table.LockedWidth = true;
 
        //relative col widths in proportions - 1/3 and 2/3
        //float[] widths = new float[] { 1f, 2f };
 
        //relative widths 1/3 1/3 1/3
        float[] widths = new float[] { 1f, 1f, 1f };
 
 
        table.SetWidths(widths);
        table.HorizontalAlignment = 0;
        //leave a gap before and after the table
        table.SpacingBefore = 20f;
        table.SpacingAfter = 30f;
 
        PdfPCell cell = new PdfPCell(new Phrase("Products 2"));
        //cell.Colspan = 2;
        cell.Colspan = 3;
        cell.Border = 0;
        cell.HorizontalAlignment = 1;
        table.AddCell(cell);
 
 
        String MyConString = "SERVER=xxx;DATABASE=xxx;UID=xxx;PASSWORD=xxx;";
        
 
        // Create the Connectionstring
     // PersistSecurityInfo = false means that the password is not displayed in the

Thanks for your help. It is so simple when you know how!!
Was thinking on the lines of nested tables, etc, but your solution works perfectly.
