[Fabrice Couvreur]

Small correction :

\starttext

\startluacode
     function Binom(n,k)
       if k > n then
             return 0
       elseif (n == 0 or k == 0) then
             return 1
       else
             return (n*Binom(n-1,k-1))/k
       end

    end

    context.startxtable({"align={middle,lohi},
width=1cm,offset=0.8ex,bodyfont=9pt"})
    for i = 0, 9 do
          context.startxrow({"background=color,backgroundcolor=cyan"})
            for j = 0, i do
                  context.startxcell()
                     context(Binom(i,j))
                  context.stopxcell()
             end
          context.stopxrow()
    end
   context.stopxtable()
