[racket-dev] scribble tables with centered cells

I'd like to produce, with scribble, output similar to what this latex produces:

\begin{tabular}{|c|c|c|}
Header1 & Header2 & Header3
11 & 17 & 29
\end{tabular}

However, I can't seem to figure out how.  First, how can I make the
elements centered?  There doesn't seem to be a way to control the
generated column attributes - putting the 'center style in the
`table-columns' style property just wraps the *entries* in \center{},
which produces bizarre latex errors instead.  Second, how can I insert
the dividers?
