Sub Articulo 99.0

    The table environment puts all its content on a single page, no
matter if it runs off the bottom. The supertabular environment is
designed to break a long table across pages. You use one or the other,
but not one enclosed in the other. So the short answer is: don't use
supertabular within table.
    You might want to take a look at the xtab package which reduces some
of the infelities of supertabular.
