Hi,
I'm trying to fill an array using lua. So far it works but then I don't
know if it's possible.
Thanks
Fabrice
\startluacode
context.startxtable({"align={middle,lohi},bodyfont=9pt,framecolor=black"})
context.startxrow({"background=color,
backgroundcolor=lightgray"})
context.startxcell({"nx=4"})
context("Units digit of")
context.stopxcell()
context.stopxrow()
context.startxrow()
context.startxcell({"width=1cm"})
context("\\im{a}")
context.stopxcell()
context.startxcell({"width=1cm"})
context("\\im{a²}")
context.stopxcell()
context.startxcell({"width=1cm"})
context("\\im{b}")
context.stopxcell()
context.startxcell({"width=1cm"})
context("\\im{2b²}")
context.stopxcell()
context.stopxrow()
for i = 0, 9 do
context.startxrow()
context.startxcell()
context(i)
context.stopxcell()
context.stopxrow()
end
context.stopxtable()
