title: PdfPTable.DefaultCell.Padding seems doesn't work
body: <p>I am trying to define the Padding of a serie of columns that will be pushed inside my PdfPTable...</p>
  
  <p>this is my code:</p>
  
  <pre><code>PdfPTable table = new PdfPTable(6);
  table.WidthPercentage = 100;
  table.SetWidths(new float[]{25, 25, 16, 11, 11, 11});
  table.DefaultCell.Padding = 3;
  </code></pre>
  
  <p>There are something wrong, because when the table is generated, it does not have padding in anywhere.</p>
  
  <p>Thank you in advance.</p>
