Supposing you are using XSLT2, this seems like a textbook example of
when to use xsl:next-match; the higher priority "outer" match creates
the wrapper, the normal-priority "inner" match creates the table.

Generally, I suspect this is a case where making the table creators
callable named templates might not be what you want; it compels you to
manage the logic of which table to create when.  If you could do that
via source document template matches, a whole lot of the headache
vanishes into the XSLT processor's domain.
