tfoot — A table footer consisting of one or more rows.
tfoot (db.cals.tfoot) ::=
Footer rows are always rendered at the end of the table, despite their logical placement near the beginning.
This element is expected to obey the semantics of the CALS Table Model Document Type Definition [calsdtd]. Footer rows are often presented in an alternate typographic style, such as boldface.
In paged media, if a table spans across multiple pages, footer rows are printed on the bottom of each page.
In our experience, relatively few formatters handle footer rows correctly.
