Hi,
I’d like to typeset a matrix with vertical and horizontal lines like so:
starttext
\startformula
\startmatrix
\HL
\VL 16 \VL 3 \VL 2 \VL 12 \VL\NR
\HL
\VL 5 \VL 10 \VL 11 \VL 8 \VL\NR
\HL
\VL 9 \VL 6 \VL 7 \VL 12 \VL\NR
\HL
\VL 4 \VL 15 \VL 14 \VL 1 \VL\NR
\HL
\stopmatrix
\stopformula
\starttable[|c|c|c|c|]
\HL
\VL $16$ \VL $3$ \VL $2$ \VL $12$ \VL \FR
\HL
\VL $5$ \VL $10$ \VL $11$ \VL $8$\VL \SR
\HL
\VL $9$ \VL $6$ \VL $7$\VL $12$ \VL\SR
\HL
\VL $4$ \VL $15$ \VL $14$ \VL $1$ \VL\SR
\HL
\stoptable
\stoptext
In the matrix version, the horizontal lines extend too far to the left.
Ideally, I would like the cells to be squares, with the entries centered.
Thanks for any suggestions!
Matthias

You can try \VC instead of \VL for the first column. Also, square
cells might be easiest(?) to get with natural tables.

Thanks!
Now, I would like to have arrows between cells. I have tried using overlays (see below), and I understand that an overlay is centered within the cell. How do I move the arrow so that it points from 6 to 7, for instance?
(Starting a little to the right and above the 6, ending below and to the left of the 7)

Maybe https://www.pragma-ade.com/general/manuals/metafun-p.pdf,
section 5, Positional graphics, is what you look for?

Thanks again. This is exquisite, truly.
One of the many things I like about using ConTeXt is that whenever I try to do something new, I learn amazing things I didn’t even know were possible.
