title: iText: PdfTable cell vertical alignment
body: <p>I'm trying to vertical align my headet cell text to be in the middle of the cell height.</p>
  
  <p>This is my code:</p>
  
  <pre><code>    PdfPCell c1 = new PdfPCell(cerate_phrase("" ,regular_bold ));
      c1.setHorizontalAlignment(Element.ALIGN_CENTER);
      c1.setVerticalAlignment(Element.ALIGN_MIDDLE);
      c1.setBackgroundColor(BaseColor.LIGHT_GRAY);
      table_.addCell(c1);
