With natural tables I can define a color, tell the table to have to
use color backgrounds and turn the frame off and get every odd row in
all my tables will have that color for the background.
========== Example
============================================================
\definecolor[grayback][r=.8,g=.8,b=.8]
\setupTABLE[background=color,frame=off]
\setupTABLE[row][odd][backgroundcolor=grayback]
========== End of Example
=====================================================
Can I get this same effect with extreme tables?
My first try with extreme tables looked like this:
========== Example
============================================================
\definecolor[tablebackground][r=.8,g=.8,b=.8]
\setupxtable[background=color,frame=off]
\setupxtable[row][odd][backgroundcolor=tablebackground]
========== End of Example
=====================================================
That didn't seem to have any effect.
Is there a way to have every odd row of every table in my document
have color background?
\startuseMPgraphic{xtablerow}
     fill OverlayBox withcolor "gray";
\stopuseMPgraphic
\defineoverlay
   [xtablerow]
   [\ifodd\currentxtablerow
      \useMPgraphic{xtablerow}%
    \fi]
\starttext
\startxtable[frame=off,background=xtablerow]
\dorecurse{20}
   {\startxrow
      \startxcell Column 1 \stopxcell
      \startxcell Column 2 \stopxcell
    \stopxrow}
\stopxtable
\stoptext
