How not to break the page on iTextSharp split my table into two pages

Question

I would like to have my pdf put on the next sheet the table that did not have enough space in the last and did not divide this table in the two sheets.

  if (reader.HasRows)
        {
            while (reader.Read())
            {
                servico.idVenda = reader.GetInt32(0);

                if (servico.idVenda != idVendaOld)
                {
                    PdfPTable tableTotal = new PdfPTable(3);
                    float[] colsTableTotal = { 14, 3, 20 };
                    tableTotal.SetWidths(colsTableTotal);
                    tableTotal.WidthPercentage = 100f;
                    tableTotal.PaddingTop = 5;

                    tableTotal.DefaultCell.Border = PdfPCell.BOTTOM_BORDER;


                    tableTotal.AddCell(getNewCell("Total:", titulo, Element.ALIGN_LEFT, 2, PdfPCell.BOTTOM_BORDER, preto, branco));
                    tableTotal.AddCell(getNewCell(somaSubTotal.ToString("c"), font, Element.ALIGN_LEFT, 2, PdfPCell.BOTTOM_BORDER, preto, branco));
                    tableTotal.AddCell(getNewCell(somaTotal.ToString("C"), font, Element.ALIGN_LEFT, 2, PdfPCell.BOTTOM_BORDER, preto, branco));

                    somaTotal = 0;
                    somaSubTotal = 0;

                    if (contador != 0)
                    {

Answer 1

You can indicate that the object or certain lines must remain together

PdfPTable tableUltimoTotal = new PdfPTable(3);
tableUltimoTotal.KeepTogether = true;
//E ou...
tableUltimoTotal.KeepRowsTogether(0);
