I think "purpose" would include what conclusions might be drawn from
a quick look at the table.  I don't think this really covers structure
at all.

I've never understood the obsession with centring text on web pages, but
columns of figure should never be centred; they should be decimal 
point aligned, which, without style sheets, probably means right

thead is fairly irrelevant, as it is more to do with multi-page printing/
display.  I don't seen any harm in doing this properly, but what I think
you need here is th on all the horizontal and vertical headings.  For
a user agent that complies with section 11.4.3 of the HTML 4 specification,
headers is likely to be unecessarily verbose.

You've also logically got column groups, although, except for shading
purposes, you might not gain much from making them explicit.
