Thanks Hans and Wolfgang.
@Wolfgang: your solution is clearer, but unfortunately it works only for
this MWE. In the real case the triangle extends over 2 rows, but the
table has more than 2 rows.
I tried grouping the first two rows in a
\bTABLEbody[background=triangle], but it doesn't work.
How about nested tables:
\starttext
\bTABLE[width=1cm,height=1cm]
\bTR
\bTD A \eTD
\bTD B \eTD
\bTD C \eTD
\bTD E \eTD
\eTR
\bTR
\bTD E \eTD
\bTD[nc=2,nr=2,strut=no,align={middle,lohi}] {\bTABLE
\bTR \bTD[nc=2] X \eTD \eTR
\bTR \bTD Y \eTD \bTD Z \eTD \eTR
\eTABLE} \eTD
\bTD H \eTD
\eTR
\bTR
\bTD I \eTD
\bTD L \eTD
\eTR
\bTR
\bTD M \eTD
\bTD N \eTD
\bTD O \eTD
\bTD P \eTD
\eTR
\eTABLE
\stoptext
@both: \setupoverlay[hoffset=...,voffset=...]?
\setupframed[backgroundhoffset=...,backgroundvoffset=...] (\bTD inherits
from \framed)?
Or maybe a method in MP to set the bounding box of the resulting overlay?
setbounds in combination with leftenlarged, topenlarged etc.
\setupframed has already a backgroundoffset option, whose value can be:
- a DIMENSION (an offset that is both horizontal and vertical)
- a "frame": what does it mean? (I looked into pack-rul.mkiv, with no
results)
ConTeXt uses the value from the frameoffset key for backgroundoffset.
\startuseMPgraphic{frameborder}
draw OverlayBox withcolor blue ;
\stopuseMPgraphic
\defineoverlay[frameborder][\useMPgraphic{frameborder}]
\setupheader[state=high]
\setupfooter[state=high]
\starttext
\setupframed
[width=4cm,
height=4cm,
offset=1cm]
\framed{}
\framed[frame=off,background=frameborder]{}
\framed[frameoffset=-5mm]{}
\framed[frameoffset=-5mm,frame=off,background=frameborder]{}
\framed[backgroundoffset=-5mm,frame=off,background=frameborder]{}
\framed[frameoffset=-5mm,backgroundoffset=frame,frame=off,background=frameborder]{}
\stoptext
