Dear All (a last question for today…)
I am following the example from the wiki at
https://wiki.contextgarden.net/Tables/Natural_tables_with_TABLE#Diagonal_rules
The first part is just copied, and works fine.
I would like the cells to be perfect squares, which is why I added \setupTABLE
[start] [width=.8cm, height=.8cm].
That works, too, but the letter a from the diagonal label is now in the second
row. I don’t know whether I need to modify the definition of
DiagonalLabel, or my setupTABLE isn’t right.
Thanks (again, and again, and again)!

rightcorner := (\overlaywidth-rulethickness, rulethickness);
draw leftcorner -- rightcorner;
