see attached ... it's more that you overload Eleve ... an alternative is
to make a function that gets that table as (then local) argument but I
don't want to touch your code too much
the function wrapper sort of delays (immediate evaluation is a general
problem, of function driven typesetting, which is why in the end a pure
function driven one is not better / easier than tex)
