Hallo Wolf[gang],

...

\setupcolors[state=start] \starttext \starttable[ o1 | \{C{red} |] \VL red \VL\SR \stoptable \stoptext

This was an older example which worked some years ago (see: http://www.ntg.nl/pipermail/ntg-context/2006/020803.html), but is not working anymore.

What is the problem here?

I can' help you to fix the original keys (need to be done by Hans) but you could define your own key.

\NewFormatKey W#1% {\ReadFormatKeys b{\localstartcolor[#1]\{} a{\}\localstopcolor}}

\setupcolors[state=start] \starttext \starttable[o1|W{red}c|] \VL red \VL\SR \stoptable \stoptext

Regards, Wolf

It is allways nice to learn something new. Thank you! Wolfgang
