Hi Malte,
1. The top left cell is divided in two by a diagonal line with separate text into each triangle
This should get you started: http://article.gmane.org/gmane.comp.tex.context/67721
That solution is very hackish and the result ugly. Here is a more clean solution. It has (at least ) one caveat: Because the first tabulate column is set in paragraph mode, it will eat up as much space as *possible*, in contrast to occupying as much space as *necessary*. That is why the width of the column has to be set explicitly. \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 [after={\blank[\frameddimension{offset}]}] \starttabulate [|p|r|] \NC \NC #2 \NC\NR \NC #1 \NC \NC\NR \stoptabulate } \starttext \setupTABLE [1] [width=2cm] \bTABLE \bTR \bTD [background=DiagonalRule] \DiagonalLabel{Foo}{Bar} \eTD \bTD Second \eTD \bTD Third \eTD \eTR \bTR \bTD Alpha \eTD \bTD Beta \eTD \bTD Gamma \eTD \eTR \eTABLE \stoptext Marco
