At least on MacOS X, 'man tbl' actually works (but there is not a separate
tbl command, true).  The man page says:

     The tbl language formats tables.  It is used within mdoc(7) and man(7)
     pages.  This manual describes the subset of the tbl language accepted by
     the mandoc(1) utility.

It looks like to me that tbl format is handled directly by mandoc.  E.g.,
this works:

mandoc -man <<EOF
.TS
[...]
.TE
EOF
