yes. very easy. just render it to a printer.
void QWidget::render ( QPaintDevice * target, const QPoint & targetOffset =
QPoint(), const QRegion & sourceRegion = QRegion(), RenderFlags renderFlags =
RenderFlags( DrawWindowBackground | DrawChildren ) )
or the more complex way if you want to play around with it before printing,
just grab it to a pixmap:
QPixmap QPixmap::grabWidget ( QWidget * widget, int x = 0, int y = 0, int
width = -1, int height = -1 ) [static]

Neither of the two will work when the table has more data than fits onto
the screen.

true. i'd try QScrollArea::widget() then.

No, you'll have to use the model to iterate over the table data and
"paint" that on the QPrinter with a QPainter yourself. Or you could
create a QTextDocument with a table on it and then use
QTextDocument::print()

uh no. you can easily just use the delegate if my other idea doesn't work.
void QItemDelegate::paint ( QPainter * painter, const QStyleOptionViewItem &
option, const QModelIndex & index ) const [virtual]
