 * Mixed table contents:
 * Demonstrate how to place various kinds of contents in table cells spanning
 * one or more columns or rows
 * 
 * Create a table with various kinds of contents. 
 * Place a text line spanning several columns and colorize the background of the
 * cell.
 * Place a text line and a Textflow in two neighbour cells of the same row and
 * vertically align them so that they have the same distance from the left and
 * upper cell borders.
 * Place an image in a cell spanning several rows and place a text line on top
 * of it in the same cell.
 * 
 * Required software: PDFlib/PDFlib+PDI/PPS 9
 * Required data: image file

         * this reason use "fontsize={capheight=6}" which will approximately
         * result in a font size of 8 points and (along with "margin=4"), will
         * sum up to an overall height of 14 points corresponding to the
         * "rowheight" option. 
         * Since the cell doesn't cover a complete row but only two of
         * three columns it cannot be filled with color using on of the
