making a long cell in another row in PDF - itext

Question

I have an iTextSharp Table with 5 columns. After each row of 5 cells I want to add another cell in another row with only one column (since the length of this cell is too long).
I tried to add 6th cell but the layout is not what I want,
It is like:
first row: the 5 cells of record 1
second row :the 6th cell of record 1
then line(BORDER)
3th row: the 5 cells of record 2
4th row :the 6th cell of record 2
and here is my code
it.Font tableCellFont = new it.Font(testBaseFont, 7, it.Font.NORMAL, it.Color.BLACK);
it.Font tableCellBoldFont = new it.Font(testBaseFont, 7, it.Font.BOLD, it.Color.BLACK);
it.Font tableHeaderFont = new it.Font(testBaseFont, 8, it.Font.BOLD, it.Color.BLACK);
//Create new PDF document
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 = it.Table.TOP_BORDER | it.Table.BOTTOM_BORDER;
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("Name", tableHeaderFont));
logTable.AddCell(new it.Phrase("Country", tableHeaderFont));
logTable.AddCell(new it.Phrase("City", tableHeaderFont));
logTable.AddCell(new it.Phrase("Job", tableHeaderFont));
logTable.AddCell(new it.Phrase("Age", tableHeaderFont));
logTable.AddCell(new it.Cell(new it.Phrase("Martin", tableCellFont)));
logTable.AddCell(new it.Phrase("Italy", tableCellFont));
logTable.AddCell(new it.Phrase("Torino", tableCellFont));
logTable.AddCell(new it.Phrase("Software developer", tableCellFont));
logTable.AddCell(new it.Phrase("29", tableCellFont));
//here I'd like to insert a row
logTable.AddCell(new it.Cell(new it.Phrase("Jack", tableCellFont)));
logTable.AddCell(new it.Phrase("U.S.A", tableCellFont));
logTable.AddCell(new it.Phrase("New York", tableCellFont));
logTable.AddCell(new it.Phrase("Manager", tableCellFont));
logTable.AddCell(new it.Phrase("50", tableCellFont));
//here I'd like to insert a row
doc.Add(logTable);
doc.Close();

(I have to put the same warning in as your previous question for future readers.)
Table is no longer support nor is the version of iTextSharp that you are using, you should switch to PdfPTable instead.
However, what you want to do is set the ColSpan on your cell that you want to cross multiple columns.
var t = new iTextSharp.text.Table(5);
t.AddCell("A");
t.AddCell("B");
t.AddCell("C");
t.AddCell("D");
t.AddCell("E");
t.AddCell(new Cell("This is my long text") { Colspan = 5 });
Or, if you're using an older version of C#:
var c = new Cell("This is my long text");
c.Colspan = 5;
t.AddCell(c);
EDIT
To change the borders, the easiest thing to do is just change the DefaultCell properties when needed.
//Turn off borders
t.DefaultCell.Border = Table.NO_BORDER;
t.AddCell("A");
t.AddCell("B");
t.AddCell("C");
t.AddCell("D");
t.AddCell("E");
//Turn bottom borders on
t.DefaultCell.Border = Table.BOTTOM_BORDER;
t.AddCell(new Cell("This is my long text") { Colspan = 5 });
//Turn borders off again
t.DefaultCell.Border = Table.NO_BORDER;
t.AddCell("F");
t.AddCell("G");
t.AddCell("H");
t.AddCell("I");
t.AddCell("J");
