I'm trying to add a table as a footer containing all the copyright text, page number etc. But I can't find any supporting method that'll accept a PdfPTable
For a phrase there is code like:
ColumnText.showTextAligned(writer.getDirectContent(),
Element.ALIGN_CENTER, new Phrase(
String.format("%d", document.getPageNumber())),
(document.getPageSize().getLeft() + document.getPageSize().getRight())/2,
document.getPageSize().getBottom() + 18, 0);
The PdfPTable
class has a method writeSelectedRows()
that can be used to add (a selection of columns and) rows at an absolute position.
Examples:
- http://itextpdf.com/examples/iia.php?id=89 adds rows at an absolute position.
- http://itextpdf.com/examples/iia.php?id=90 adds a selection of columns/rows at an absolute position.
- http://itextpdf.com/examples/iia.php?id=91 an alternative solution where you wrap a table in a
ColumnText
object.
The examples posted by Bruno are a good pointer, here's an example without magic numbers:
private void writeFooterTable(PdfWriter writer, Document document, PdfPTable table) {
final int FIRST_ROW = 0;
final int LAST_ROW = -1;
//Table must have absolute width set.
if(table.getTotalWidth()==0)
table.setTotalWidth((document.right()-document.left())*table.getWidthPercentage()/100f);
table.writeSelectedRows(FIRST_ROW, LAST_ROW, document.left(), document.bottom()+table.getTotalHeight(),writer.getDirectContent());
}
This will write the PdfPTable within the document margins at the bottom overlapping any text you have at the bottom. If you wish to write the table in the margin, use: document.bottom()
instead of document.bottom()+table.getTotalHeight()
.
Header/Footer Example
As a relevant note if you're following the example on this link, the "art" box does not appear to be required and the magic numbers 36, 54, 559, 788 correspond to:
document.left(), document.bottom(), document.right(), document.top()
To implement a custom footer you need to implement the PdfPageEventHelper.
