I have a table where its cells background are partially transparent. The
cells' background are set using a CellEvent (see
http://www.nabble.com/Different-transparency-for-cells-in-PdfPtable-td21511310.html).
However, there is a border drawn for the cells even when I set the
borderWidth and border to 0. How do I get rid of this border?
Please see example program below:
