Прямоугольные границы легко определить с помощью PdfPCellEvent.Но у меня проблемы с номерами страниц.
A PdfPCellEvent - действительно, путь, и во время вызова метода события ячейки вам просто нужно получить текущий PdfWriter.PageNumber значение, например, вот так:
public class CellEvent : IPdfPCellEvent
{
public CellEvent(PdfWriter writer, String name)
{
this.writer = writer;
this.name = name;
}
public void CellLayout(PdfPCell cell, Rectangle position, PdfContentByte[] canvases)
{
Console.WriteLine("Cell {0} on page {1} at {2}, {3} - {4}x{5}", name, writer.PageNumber, position.Bottom, position.Left, position.Width, position.Height);
}
PdfWriter writer;
String name;
}
Используется так:
using (FileStream fileStream = new FileStream(@"Table-CellLayoutInformation.pdf", FileMode.Create))
using (Document document = new Document())
{
PdfWriter writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
PdfPTable table = new PdfPTable(1);
table.WidthPercentage = 90;
table.SplitRows = true;
table.SplitLate = false;
for (int i = 0; i < 20; i++)
{
PdfPCell cell = new PdfPCell();
cell.CellEvent = new CellEvent(writer, i.ToString());
cell.AddElement(new Paragraph("Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

cell.AddElement(new Paragraph("Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.

table.AddCell(cell);
}
document.Add(table);
}
Я получаю вывод

Код прослушивателя событий вышеочевидно предполагает, что вы действительно рисуете таблицу, добавляя ее к соответствующему Document.Если вы нарисуете таблицу с помощью PdfPTable.WriteSelectedRows на произвольном PdfContentByte, данные, скорее всего, будут неправильными.
