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.
