How about:

\usecolors[svg]
\starttext
\ssa\bold
\starttabulate[|r|CT{red}c|c|CT{yellow}c|c|CT{green}c|c|CT{cyan}c|c|CT{blue}c|c|CT{darkmagenta}c|]
\NC   S = \NC 1 \NC + \NC 2 \NC + \NC 3 \NC + \NC 4 \NC + \NC 5 \NC + \NC 6 
\NC\NR
\NC + S = \NC 6 \NC + \NC 5 \NC + \NC 4 \NC + \NC 3 \NC + \NC 2 \NC + \NC 1 
\NC\NR
\HL[cornflowerblue]
\NC  2S = \NC 7 \NC + \NC 7 \NC + \NC 7 \NC + \NC 7 \NC + \NC 7 \NC + \NC 7 
\NC\NR
\stoptabulate
\stoptext

[NTG-context] Sum and mathalignment

2021-11-30 Thread Alexandre Christe via ntg-context 
Dear list,

[image: image.png]

What I've done is to play with mathalignment and \framed. Here is a MWE:

\starttext
\defineoverlay[midrule][{\blackrule[height=.02cm,width=5.5cm]}]

\framed[frame=off,background=midrule,boffset=.65cm]{\startformula

\startmathalignment[n=12,align={middle,middle,middle,middle,middle,middle,middle,middle,middle,middle,middle,middle}]
\NC \NC S_6 \NC= \NC 1 \NC+ \NC 2 \NC+ \NC\dots \NC+ \NC 5 \NC+ \NC 6
\NR
\NC + \NC S_6 \NC= \NC 6 \NC+ \NC 5 \NC+ \NC\dots \NC+ \NC 2\NC+ \NC 1
\NR
\NC\NC 2S_6 \NC= \NC 7 \NC+ \NC 7 \NC+ \NC\dots \NC+ \NC 7 \NC+ \NC 7
\NR
  \stopmathalignment
\stopformula}
\stoptext

Is there a simpler way to typeset something like this?

Thanks in advance!
