Hi,
I have seen this example from the book. I am not sure sure what I missed.
In this example we dont have any PdfPTableEvent as well as PdfpCellEvent
both of which sets the background canvas.
I noticed that cell events get called before table events. So is it a
possibility, that the table background is "overlapping" the cell background
settings.
Thanks you for your patience.
Subhro.
