Currently the width is ignored. We were thinking 'too far ahead' 7
years ago and envisaged it might be used one day when packing boxes

Never tried it but it's isn't supposed to do that. It's just to
create extra vertical space between elements, when spaceBefore and
spaceAfter on paragraphs don't give you enough. the packing algorithm
just sees it and moves down.

Tables are centered by default but have an hAlign attribute to control
their overall position (assuming they are narrower than the enclosing
from reportlab.lib.enums import TA_LEFT, TA_CENTER, TA_RIGHT
t = Table(...., hAlign=TA_LEFT)
You can pass it to the constructor, or set it on the table after construction.
