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

       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()

Hello,
I want to display the values of Pascal's triangle in a table.
Unfortunately my knowledge of Lua is not sufficient to run this code.
Thank you.

Are you sure you want to use context(...) here?
    end

    context.startxtable({"align={middle,lohi}, width=1.2cm,offset=0.8ex,bodyfont=9pt"})
    context.startxrow({"background=color,backgroundcolor=green"})
    for i = 0, 10 do
      for j = 0, i do
          context.startxcell()
            context(Binom(i,j))
          context.stopxcell()
      end
    end
    context.stopxrow()

context.stopxtable()
