Hello all.
The following code (tested at contextgarden) illustrates my current problem:
--
\definetextbackground[TestBackground]
[leftoffset=1em,rightoffset=1em,topoffset=8pt,
bottomoffset=8pt,frame=on,location=paragraph]
\starttext
\starttextbackground[TestBackground]
Some text first, which behaves perfectly, and then a table:
\vbox{\bTABLE
\setupTABLE[column][1][width=0.3\textwidth]
\setupTABLE[column][2][width=0.7\textwidth]
\bTR\bTD I was hoping\eTD
\bTD that this table would make itself narrower according to the
background offsets, like the text does. But it doesn't.\eTD\eTR
\eTABLE}
\stoptextbackground
\stoptext

The key is in the spec for column widths. I would like all the widths to
be specified proportionally, but I need the right hook. I have tried
\textwidth and \makeupwidth but neither seem to recognise the offsets
introduced by the background. What I'd really like is a generalised
solution, so that all tables just work no matter where they occur.
So - is there a parameter which represents the current width of the
layout area, taking into account itemisations, textbackgrounds and
anything else? Thanks.
[And thanks Hans for the earlier reference to details.pdf, which I am
still trying to understand in order to allow my tables to extend into
the margin. I'm working on it!]

I came up with a rather ugly kludge which solves my immediate problem
but might not be best. I created a new dimen, \RealWidth, and before
each table I set it to the value of \textwidth minus leftskip minus
rightskip. In other words, I did this:
--
\newdimen\RealWidth
\definetextbackground[TestBackground]
[leftoffset=1em,rightoffset=1em,topoffset=8pt,
bottomoffset=8pt,frame=on,location=paragraph]
\starttext
\starttextbackground[TestBackground]
Some text first, which behaves perfectly, and then a table:
\leavevmode\RealWidth=\textwidth\advance\RealWidth
by-\leftskip\advance\RealWidth by-\rightskip\bTABLE
\setupTABLE[column][1][width=0.3\RealWidth]
\setupTABLE[column][2][width=0.7\RealWidth]
\bTR\bTD I was hoping\eTD
\bTD that this table would make itself narrower according to the
background offsets, like the text does. And now it does!\eTD\eTR
\eTABLE}
\stoptextbackground
\stoptext

This produces what I want as far as I have tested it. I'm not sure it's
the best or most comprehensive solution though.
