title: Add PdfPCell to Paragraph
body: <p>I'm trying to add a TextField (acrofield) in the middle of a Paragraph sentence using iTextSharp. An example would be "The Effective Date is [Day] day of [Month], [Year] that this will begin."</p>
  
  <p>Things I have tried:</p>
  
  <pre><code>Paragraph para1 = new Paragraph();
  para1.Add(New Phrase("The Effective Date is",fontBold));
      //The next line is where it breaks, "Insertion of illegal Element: 30"
  para1.Add(CreateTextField("Day",1,0)); //this function returns a PdfPCell.
  </code></pre>
  
  <hr>
  
  <pre><code>PdfPCell tempCell = new PdfPCell();
  tempCell.AddElement(new Phrase("The Effective Date is",fontBold));
      //the next line breaks as well, "Element not allowed."
  tempCell.AddElement(CreateTextField("Day",1,0));
  </code></pre>
  
  <hr>
  
  <pre><code>Paragraph para1 = new Paragraph();
  para1.Add(New Phrase("The Effective Date is",fontBold));
  para1.AddSpecial(CreateTextField("Day",1,0));
      //This doesn't generate an error, but the TextField is not displayed on PDF
  </code></pre>
  
  <hr>
  
  <pre><code>Paragraph para1 = new Paragraph();
  PdfPTable tempTable = new PdfPTable(1);
  para1.Add(New Phrase("Hello",fontBold));
  tempTable.AddCell(CreateTextField("Day",1,0));
  para1.Add(tempTable);
  para1.Add(New Phrase("World",fontBold));
      //This doesn't generate an error, but the TextField is not displayed on PDF
  </code></pre>
  
  <p>I know the CreateTextField(...) works because I am using it in several other places on the page.</p>
  
  <p>How can I add a TextField inline with other text without using tables and tediously trying to manipulate cell size to accommodate what I need?</p>
  
  <p>Thanks for the help!</p>
