But where's the path?
What makes you believe this will actually draw something?
It just doesn't make sense...
As you can see in the attachment it put the text below the table instead
of overlaying it.
Of course! That's how you programmed it!
Maybe a working example would be easier to understand.
Sigh...
The fact that you don't understand why you need to paint
a path before you STROKE or FILL it (as is clearly explained
in the book), and the fact that you throw away everything
that is already in the cell by using setPhrase, a method
that is NOT EVEN MENTIONED in the book, really gives me
the impression you are pulling my leg here, but against
better judgment, see the attachment for a working example
(of course I have no idea if that's actually what you want
to do; your original code was very unclear).
