* Table invoice:
* Create an invoice using the table feature
*
* Create an invoice by importing a background PDF page with the company's
* stationery header. Output the customer's address data as well as a table
* listing all items ordered including their quantities and prices. If the table
* spans several pages output a subtotal after each table instance. To retrieve
* the last row having been output in a table instance use info_table() with the
* "lastbodyrow" option. In the last table row, output the total at the end of
* the table. Output some final text directly after the table. Use info_table()
* with the "height" option to retrieve the exact end position of the table.
*
* Required software: PDFlib+PDI/PPS 9
* Required data: PDF file
