title: iTextSharp - Use Colspan with PdfPRow
body: <p>I am able to create multiple rows if they contain the same number of columns:</p>
  
  <pre><code>table = new PdfPTable(3);
  
  var firstRowCell1 = new PdfPCell( new Phrase ("Row 1 - Column 1"));
  var firstRowCell2 = new PdfPCell( new Phrase ("Row 2 - Column 2"));
  var firstRowCell3 = new PdfPCell( new Phrase ("Row 3 - Column 3"));
  PdfPCell[] row1Cells = { firstRowCell1, firstLineRow2, firstRowCell3 };
  var row1 = new PdfPRow(row1Cells);
  table.Rows.Add(row1);
  
  var nextRowCell1 = new PdfPCell( new Phrase ("Row 2 - Column 1"));
  var nextRowCell2 = new PdfPCell( new Phrase ("Row 2 - Column 2"));
  var nextRowCell3 = new PdfPCell( new Phrase ("Row 2 - Column 3"));
  PdfPCell[] row2Cells = { nextRowCell1, nextRowCell2, nextRowCell3 };
  var row2 = new PdfPRow(row2Cells);
  table.Rows.Add(row2);
  </code></pre>
  
  <p>This works fine giving me two rows each with three columns.</p>

  <p>However if I want the first row to just have one long column using Colspan it disappears:</p>
  
  <pre><code>var table = new PdfPTable(3);  
  
  var firstRowCell1 = new PdfPCell(new Phrase("Row 1 - Column 1"));
  firstRowCell1.Colspan = 3;
  PdfPCell[] row1Cells = { firstRowCell1 };
  var row1 = new PdfPRow(row1Cells);
  deptHeaderTable.Rows.Add(row1);
  
  var nextRowCell1 = new PdfPCell(new Phrase("Row 2 - Column 1"));
  var nextRowCell2 = new PdfPCell(new Phrase("Row 2 - Column 2"));
  var nextRowCell3 = new PdfPCell(new Phrase("Row 2 - Column 3"));
  PdfPCell[] row2Cells = { nextRowCell1, nextRowCell2, nextRowCell3 };
  var row2 = new PdfPRow(row2Cells);
  deptHeaderTable.Rows.Add(row2);
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/TYFO5.png" alt="enter image description here"></p>
  
  <p>There are no errors given it just simply does not render.  </p>
  
  <p>Additionally, I am aware of table.AddCell which automatically starts a new row when the table column limit is reached for the current row.  However, I want to use PdfPRow if at all possible.</p>
  
  <p>Any help would be greatly appreciated.</p>
