title: adding line between rows of table in PDF
body: <p>my code is like that, here <code>it</code> is <code>ITextSharp.Text</code>.</p>
  
  <p>I'd like to ask, if I want to add black lines between each row, how to do it?
  I tried to find the property of <code>ITEXTSharp.Text.Table</code>, but I cannot find there is any property there.</p>
  
  <pre><code>it.Document doc = new it.Document();
  PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(fileName, FileMode.Create));        
  doc.Open();
  it.Phrase p = new it.Phrase("item1", new it.Font(testBaseFont, 14, it.Font.BOLD, it.Color.BLACK));
  p = new it.Phrase("item2", new it.Font(testBaseFont, 14, it.Font.BOLD, it.Color.BLACK));
  p.Leading = 2;
  doc.Add(p);
  it.Table logTable = new it.Table(5);
  logTable.Alignment = it.Table.ALIGN_LEFT;
  logTable.DefaultVerticalAlignment = it.Element.ALIGN_MIDDLE;
  logTable.Width = 100;
  logTable.Border = it.Table.TOP_BORDER | it.Table.BOTTOM_BORDER;
  logTable.BorderWidth = 0.5f;
  logTable.DefaultCellBorder = 0;
  logTable.Cellspacing = 2;
  logTable.Cellpadding = 0;
  logTable.DefaultCellBackgroundColor = it.Color.WHITE;
  logTable.SetWidths(new int[] { 20, 20, 20, 20, 20 });
  //Write column headers
  logTable.AddCell(new it.Phrase("Column1", tableHeaderFont));
  logTable.AddCell(new it.Phrase("Column2", tableHeaderFont));
  logTable.AddCell(new it.Phrase("Column3", tableHeaderFont));
  logTable.AddCell(new it.Phrase("Column4", tableHeaderFont));
  logTable.AddCell(new it.Phrase("Column5", tableHeaderFont));
  
  logTable.AddCell(new it.Cell(new it.Phrase("1", tableCellFont)));
  logTable.AddCell(new it.Phrase("12", tableCellFont));
  logTable.AddCell(new it.Phrase("13", tableCellFont));
  logTable.AddCell(new it.Phrase("14", tableCellFont));
  logTable.AddCell(new it.Phrase("15", tableCellFont));
  
  
  logTable.AddCell(new it.Cell(new it.Phrase("2", tableCellFont)));
  logTable.AddCell(new it.Phrase("22", tableCellFont));
  logTable.AddCell(new it.Phrase("23", tableCellFont));
  logTable.AddCell(new it.Phrase("24", tableCellFont));
  logTable.AddCell(new it.Phrase("25", tableCellFont));
  
  doc.Add(logTable);
  doc.Close();
