Description
The tfoot is
an odd element in that it seems to defy logic. Common sense would suggest
that if you have table headers wrapped in the thead
element, followed by the body of the table wrapped in a tbody, the footer content should naturally follow that . But
this is not the case. Oddly enough, like a biology experiment gone wrong,
the correct order for these elements is head, foot, body (or
thead, tfoot,
tbody, to use the correct element names).
There
are reasons for this apparently illogical approach. By providing the
table’s header and footer content up-front in the thead
and tfoot elements, respectively, the browser has the
opportunity to render that information first, then incrementally fill the
body of the table. This approach is often desirable when you’re accessing
the content over a very slow connection, or when the table runs to a
considerable length (or both!).
Despite the tfoot
content coming before the body of the table, the browsers we tested
correctly identify that it’s intended as footer content, and place it in
the appropriate location—at the end of the table—as Figure 1 shows.
Use This For …
This element is used to group the table’s footer area (which may be a summary, an addition of column values, or some call to action based on the preceding content).

I think the main reason for having TFOOT appear before TBODY is to do with printing. A user agent may render the header and footer on each page when a table with many rows is printed. In order to avoid having to parse the entire table before starting to render it, the TFOOT needs to appear before the TBODY.
