I said:
So - is there a parameter which represents the current width of the layout area, taking into account itemisations, textbackgrounds and anything else? Thanks.

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.
