The following code does what I want:
\blank
\SetTableToWidth{\textwidth}
\starttable[|lp(0.90\textwidth)|]
Some text \SR
\SR
\HL
\SR
\HL
\SR
\HL
\SR
\HL
\stoptable
\blank
I would think that the following code is equivalent:
\blank
\SetTableToWidth{\textwidth}
\starttable[|lp(0.90\textwidth)|]
Some text \SR
\dorecurse{4}{
\SR
\HL
}
\stoptable
\blank
But it is not. I get:
Underfull \hbox (badness 10000) in alignment at lines 39--49
[][][][][]
! Misplaced \noalign.
\TABLEnoalign ->\noalign
\bgroup \let \noalign \relax \let \next =
\insertTABLEtail ->\TABLEnoalign
{\global \settrue \preventTABLEbreak \globa...
\stoptable ->\chuckTABLEautorow \insertTABLEtail
\TABLEnoalign {\globalletem...
l.60 \stoptable
and h gives:
I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.
What am I doing wrong?

But if you only want four horizontal lines, why not use \thinrules \thinrules[n=4] Also have a look at m-educat.tex (look at the example in the end of the file) which is essentially a fancy wrapper around \thinrules. I don't know if \thinrules are documented in a manual, but pack-rul.mkiv gives a few examples: \starttext A couple of examples are given below. \startbuffer \setupthinrules[n=3,inbetween=,color=gray] test test \thinrules\ test test \par test test \thinrules [color=green] test test \par test test \thinrules [height=max, depth=max] test test \par \setupthinrules[height=.9,depth=.9] test test \thinrules\ test test \par test test \thinrules [alternativevariant=b] test test \par test test \thinrules [alternativevariant=c] test test \par test test \thinrules [alternativevariant=c,inbetween=\vskip2ex] test test \par \stopbuffer \typebuffer {\getbuffer} There are a couple of alternative ways to visualize rules using backgrounds. At first sight these may look strange, but they make sense in educational settings. The alternatives are more or less compatible with the more advanced \METAPOST\ based implementation. \startbuffer[a] \setupthinrules [n=2, backgroundcolor=gray , rulethickness=1pt, colorkleur=donkerblauw, after=\blank, before=\blank] \stopbuffer \typebuffer[a] \startbuffer[b] \thinrules[alternativevariant=a] \thinrules[alternativevariant=b] \thinrules[alternativevariant=c] \stopbuffer \typebuffer[b] \getbuffer[a,b] \startbuffer[b] \thinrules[alternativevariant=a,background=color] \thinrules[alternativevariant=b,background=color] \thinrules[alternativevariant=c,background=color] \stopbuffer \typebuffer[b] \getbuffer[a,b] \startbuffer[b] \thinrules[alternativevariant=a,height=.8,depth=.8,background=color] \thinrules[alternativevariant=b,height=.8,depth=.8,background=color] \thinrules[alternativevariant=c,height=.8,depth=.8,background=color] \stopbuffer \typebuffer[b] \getbuffer[a,b] \stoptext Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 3+ messages in thread
