This looks pretty good, just a few minor nits...

I would've expected this to be "const".

I prefer single spaces for padding because I find it easier to read that
way. Also using tabs to make this look like a table has the drawback
that you run the risk of having to adjust padding for all fields when a
new field is added whose name is longer than any existing ones. Or you
have to rely on excessive padding (such as in this case) to make that
unlikely. So I don't see any advantage in this, but I don't have very
strong objections either.

Why wrap these two lines? They seem to fit on one line and within 78
columns.

"static const"?

"}," and "{" can go on the same line.

"const"?
