# [NTG-context] xtables with lua

Thanks for pointing to your context-blog: one learns always some good stuff there!

I wanted to make an observation about the last example in that page, which does not typeset correctly as expected, and also it does not work well if one wanted to make a multiplication table instead of the addition table of your examples. I think the following modification might be necessary (here for the multiplication table):

%%%%%%%
\startplacetable
\startluacode
context.bTABLE()
context.bTR()
context.bTD() context("($\\times$)") context.eTD()
for n = 1,6 do
context.bTD() context(n) context.eTD()
end
context.eTR()
for x = 1,6 do
context.bTR()
for y = 0,6 do
context.bTD()
if y == 0 then
context(x)
elseif y > 0 then
context(x*y)
end
context.eTD()
end
context.eTR()
end
context.eTABLE()
\stopluacode
\stopplacetable
%%%%%%%

Thanks again, and best regards: OK
