[NTG-context] Code lua in a table

[Fabrice Couvreur]

Hi,
I improved the code to be able to display the grid but I cannot display the
coefficients.
Thank you
Fabrice

\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=1.2cm,offset=0.8ex,bodyfont=9pt"})
    for i = 1, 10 do
          context.startxrow({"background=color,backgroundcolor=cyan"})
            for j = 1, i do
                  context.startxcell()
                     \ctxlua{context(Binom(i,j))}
                  context.stopxcell()
             end
          context.stopxrow()
    end
   context.stopxtable()

\stopluacode
