iText 表 SetKeepTogether 重复标题行

如何解决iText 表 SetKeepTogether 重复标题行

我尝试将我的表格和标题行设置为 SetKeepTogether(true)，但发生了这种情况 image，我尝试设置所有单元格 SetKeepTogether (true) 但它仍然使行中的分页符。 SetKeepWithNext 在这里有帮助吗？

clsPDfheader handler = new clsPDfheader(dtTestHeader(),document);
pdfDocument.AddEventHandler(PdfDocumentEvent.END_PAGE,handler);
document.SetMargins(30 + handler.GetTableHeight(),36,36);
Table tblChcklist = new Table(UnitValue.CreatePercentArray(new float[] { 4,35,20,20 })).SetVerticalAlignment(VerticalAlignment.MIDDLE).SetHorizontalAlignment(iText.Layout.Properties.HorizontalAlignment.CENTER).UseAllAvailableWidth().SetFont(PdfFontFactory.CreateFont(StandardFonts.HELVETICA,PdfEncodings.WINANSI,false)).SetFontSize(10);

foreach (DaTarow drS in dtS.copyToDataTable().Rows)
{
                    tblChcklist = new Table(UnitValue.CreatePercentArray(new float[] { 4,false)).SetKeepTogether(true);
                    tblChcklist.AddHeaderCell(new Cell(2,1).Add(new Paragraph($"No.").SetTextAlignment(TextAlignment.CENTER).SetHorizontalAlignment(iText.Layout.Properties.HorizontalAlignment.CENTER).SetVerticalAlignment(VerticalAlignment.MIDDLE)));
                    tblChcklist.AddHeaderCell(new Cell(2,1).Add(new Paragraph($"Seccion {drS["nombreSeccion"]}").SetBold()));
                    tblChcklist.AddHeaderCell(new Cell().Add(new Paragraph("Si").SetTextAlignment(TextAlignment.CENTER)));
                    tblChcklist.AddHeaderCell(new Cell().Add(new Paragraph("No").SetTextAlignment(TextAlignment.CENTER)));
                    tblChcklist.AddHeaderCell(new Cell().Add(new Paragraph("No Aplica").SetTextAlignment(TextAlignment.CENTER)));
                    var dtP = business.getPreguntasRevision().AsEnumerable().Where(r => r.Field<int>("idCatTipoChecklist") == idChecklist && r.Field<int>("idCatCheckListSeccion") == (int)drS["idCatCheckListSeccion"]);
                    if (dtP.Any())

                    tblChcklist.AddCell($"{drP["Pregunta"].ToString().Trim()}");
                    //3-4
                    //Si

                    }
                    tblChcklist.AddCell(new Cell(0,0).Add(new Paragraph()));
