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()

\stopluacode

\stoptext

Hi Wolfgang,

It works but why did you ask this question since I finally use context ?
Are you sure you want to use context(...) here?
How not to display the .0 ?

Remove \ctxlua:

context(Binom(i,j))
