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
<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)!
– You don’t want to use dollar notation for math anymore.
– In this case, declare the tabulate columns as inline math.
– I had to use a fixed width for the tabulate columns to get the right
distances.
– Getting rid of the tabulate is even better.
\startuseMPgraphic{DiagonalRule}
rulethickness := \frameddimension{rulethickness};
drawoptions(
withpen pencircle scaled rulethickness
withcolor \MPcolor{\framedparameter{framecolor}});
pair leftcorner, rightcorner;
leftcorner := (rulethickness, \overlayheight-rulethickness);
rightcorner := (\overlaywidth-rulethickness, rulethickness);
draw leftcorner -- rightcorner;
\stopuseMPgraphic
\defineoverlay
[DiagonalRule]
[\useMPgraphic{DiagonalRule}]
\define[2]\DiagonalLabel{%
\setuptabulate [distance=none,]
\setupinterlinespace[2ex]
