title: iTextSharp pdf table cell height issue
body: <p>I have iTextSharp 5.4.4 (nuget) and have a nice table with a barcode (ean13) and text below it.
  I have specific tablecell heights (and cell widths) because I want to print the pdf to an A4 with stickers.
  Here is the current layout:</p>
  
  <p><img src="https://i.stack.imgur.com/EU35m.png" alt="enter image description here"></p>
  
  <p>as you can see, there is a rather large gap between the ean13 code and the text below.
  here is my C# code:</p>
  
  <pre><code>PdfPCell c = new PdfPCell();
  c.FixedHeight = 21.2f * postScriptPointsPerMilimeter; // to get to accurate milimeters
  c.HorizontalAlignment = Element.ALIGN_CENTER;
  
  Paragraph p = new Paragraph();
  p.Font.Size = 6;
  Chunk code = new Chunk(dr["productcode"].ToString());
  p.Alignment = Element.ALIGN_CENTER;
  p.Add(code);
  
  BarcodeEAN ean13 = new BarcodeEAN();
  ean13.CodeType = BarcodeEAN.EAN13;
  ean13.Code = dr["ProductEan13"].ToString();
  ean13.BarHeight = 4.0f * postScriptPointsPerMilimeter;
  var a = ean13.CreateImageWithBarcode(cb, null, null);
  a.ScalePercent(90);
  
  c.AddElement(a);
  c.AddElement(p);
  
  t.AddCell(c);
  </code></pre>
  
  <p>My question is to reduce the space between the barcode and the text. I cannot see if it has something to do with the barcode's margins or the paragraph's or maybe both... hard to troubleshoot.</p>
