I'd do it as a PythonMethod or PythonScript:

output =3D '<table>\n'
column =3D 1

for item in array:
        if column =3D=3D 1:
                output =3D output + '<tr>\n'

        output =3D output + '<td>%s</td>\n' % item

        if column =3D=3D max_column:
                output =3D output + '</tr>\n'
                column =3D 1:
        else:
                column =3D column + 1

output =3D output + '</table>\n'

return output

This code is written off the top of my head, so I don't know if it works.
I do know that it won't do too well when the number of elements in the
array isn't a muliple of max_column; I'll leave that as an exercise for
the reader :-)
