Class PdfPTable

java.lang.Object
  extended bycom.lowagie.text.pdf.PdfPTable
All Implemented Interfaces:
Element

public class PdfPTable
extends Object
implements Element

This is a table that can be put at an absolute position but can also be added to the document as the class Table. In the last case when crossing pages the table always break at full rows; if a row is bigger than the page it is dropped silently to avoid infinite loops.

A PdfPTableEvent can be associated to the table to do custom drawing when the table is rendered.
