title: itextsharp how to add line height to the chunk content
body: <p>I am using the following code in .net using iTextSharp</p>
  
  <pre><code>PdfPTable Header2 = new PdfPTable(2);
  Header2.DefaultCell.Padding = 4;
  Header2.WidthPercentage = 90;
  Phrase pp4 = new Phrase();
  pp4.Add(new Chunk("  Text of the first line\n", FontFactory.GetFont("Arial", 17, iTextSharp.text.Font.BOLD, iTextSharp.text.Color.BLACK)));
  pp4.Add(new Chunk("  Text of the second line", FontFactory.GetFont("Arial", 15, iTextSharp.text.Font.ITALIC, iTextSharp.text.Color.BLACK)));
  PdfPCell hcell3 = new PdfPCell(new Phrase(pp4));
  hcell3.HorizontalAlignment = Element.ALIGN_LEFT;
  hcell3.VerticalAlignment = Element.ALIGN_TOP;
  hcell3.BorderColor = iTextSharp.text.Color.BLACK;
  hcell3.BackgroundColor = new iTextSharp.text.Color(255, 255, 255);
  Header2.AddCell(hcell3);
  </code></pre>
  
  <p>The output shows text very close to each other in various lines. I need to put up some vertical space between two lines.
  How can I achieve this in the code above?</p>
