How to create a table with 2 rows that can be used as a footer?
I want to add footer with 2 rows. The 1st row will have the document name with a background color. The 2nd row will have copyright notices. I tried to create this table using ColumnText
, but I am not able to set the background color for the row (only the text is getting background color).

You can set the background of a cell using the setBackgroundColor()
method.
Take a look at the TableFooter example:
Table table = new Table(UnitValue.createPercentArray(1)).useAllAvailableWidth();
table.setWidth(523);
Cell cell = new Cell().add(new Paragraph("This is a test doc"));
cell.setBackgroundColor(ColorConstants.ORANGE);
table.addCell(cell);
cell = new Cell().add(new Paragraph("This is a copyright notice"));
cell.setBackgroundColor(ColorConstants.LIGHT_GRAY);
table.addCell(cell);
Then if you are using iText 7 you should write the implementation of IEventHandler
and add this table to the document using Canvas
instance:
protected class TableFooterEventHandler implements IEventHandler {
private Table table;
public TableFooterEventHandler(Table table) {
this.table = table;
}
@Override
public void handleEvent(Event event) {
PdfDocumentEvent docEvent = (PdfDocumentEvent) event;
PdfDocument pdfDoc = docEvent.getDocument();
PdfPage page = docEvent.getPage();
PdfCanvas canvas = new PdfCanvas(page.newContentStreamBefore(), page.getResources(), pdfDoc);
new Canvas(canvas, pdfDoc, new Rectangle(36, 20, page.getPageSize().getWidth() - 72, 50))
.add(table);
}
}
Here it is! Make sure you define the margins of your page in such a way that the footer table doesn't overlap with the page content.
