Thanks a lot, Duncan. 

In the minimal example, I have two variables (d and beta) that create "blocks"
of rows showing similar results. Assume you have three (say, d, beta, and
alpha in columns 1, 2, and 3, respectively). I typically separate blocks with the
same d by a larger space, then blocks with the same beta with a smaller space (and
blocks with the same alphas with no space). So this would look like:

tabular(RowFactor(d, spacing=2, space=0.5) * RowFactor(beta, spacing=2,
space=0.25) * alpha ~ group * mean * Heading() * value, data=df)

... with appropriate "spacing" arguments. I find this visually quite appealing. 

Cheers,
