I am designing an Invoice document where we need to encolose the whole of the Body part within a single Rectangle. I have been unable to do it. A workaround may be to use some kind of image as in a Theme, but I would like to avoid that one. I tried to use a rectangle which starts above the Header/Body boundary and ends at below the Body/Footer boundary (as possible in some reporting applications) but it did not work. The rectangle will not stretch.
How can I achieve this?
