Interfering frames in natural tables

Interfering frames in natural tables

Hi,

the frames are interfering in the following example. How to avoid
the 2pt-2-column bottom rule also be drawn at the top?

\startsetups table
  \setupTABLE [frame=off]
  \setupTABLE [row] [first] [topframe=on]
  \setupTABLE [1]   [first] [bottomframe=on, rulethickness=2pt]
\stopsetups

\starttext
  \bTABLE [setups=table]
    \bTR\bTD[nc=2] Lorem                               \eTD\eTR
    \bTR\bTD Ipsum  \eTD\bTD Dolor    \eTD\bTD Sit     \eTD\eTR
    \bTR\bTD aaaaaa \eTD\bTD bbbbbbbb \eTD\bTD ccccccc \eTD\eTR
    \bTR\bTD dddd   \eTD\bTD eeeeeeee \eTD\bTD fffff   \eTD\eTR
  \eTABLE
\stoptext


Side question: Is it safe not to use setups and shorten the example?

\starttext
  \bTABLE
    \setupTABLE [frame=off]
    \setupTABLE [row] [first] [topframe=on]
    \setupTABLE [1]   [first] [bottomframe=on, rulethickness=2pt]

    \bTR\bTD[nc=2] Lorem                               \eTD\eTR
    \bTR\bTD Ipsum  \eTD\bTD Dolor    \eTD\bTD Sit     \eTD\eTR
    \bTR\bTD aaaaaa \eTD\bTD bbbbbbbb \eTD\bTD ccccccc \eTD\eTR
    \bTR\bTD dddd   \eTD\bTD eeeeeeee \eTD\bTD fffff   \eTD\eTR
  \eTABLE
\stoptext

Wiki ⇒ TABLES ⇒ Rules with different thickness

However, IMO it seems total overkill to use MetaPost and overlays to
draw a simple line in a table.

I agree! It is inconvenient.

Do you mean something like this ?

\startsetups table
 \setupTABLE [frame=off]
 \setupTABLE [r][1] [bottomframe=on]
 \setupTABLE [1]   [1] [bottomframe=on, rulethickness=2pt]
 \setupTABLE [1]   [2] [bottomframe=on, rulethickness=2pt]
 \setupTABLE [c][3] [bottomframe=off]
\stopsetups

\starttext
 \bTABLE [setups=table]
  \bTR\bTD\eTD\bTD\eTD\eTR
   \bTR\bTD[nc=2] Lorem                             \eTD\eTR

 \eTABLE

… and I still don't get it working. I used the example from the
wiki. The problem: The frame is drawn on *every* cell. It basically
looks like a global frame=on.

Minimal example to draw two rules in a table (44 lines, seriously?!)

\startuseMPgraphic{tableborders}
  draw leftboundary   OverlayBox withpen pensquare scaled \frameddimension  {leftrulethickness} ;
  draw rightboundary  OverlayBox withpen pensquare scaled \frameddimension {rightrulethickness} ;
  draw topboundary    OverlayBox withpen pensquare scaled \frameddimension   {toprulethickness} ;
  draw bottomboundary OverlayBox withpen pensquare scaled \frameddimension{bottomrulethickness} ;

  clip currentpicture to OverlayBox
    leftenlarged   (\frameddimension  {leftrulethickness}/2)
    rightenlarged  (\frameddimension {rightrulethickness}/2)
    topenlarged    (\frameddimension   {toprulethickness}/2)
    bottomenlarged (\frameddimension{bottomrulethickness}/2) ;

  setbounds currentpicture to OverlayBox ;

\stopuseMPgraphic

\defineoverlay [tableborders] [\useMPgraphic{tableborders}]

\startsetups tableborders

\setupTABLE
  [         background=tableborders,
                 frame=off,
      backgroundoffset=0pt,
     leftrulethickness=\framedparameter{rulethickness},
    rightrulethickness=\framedparameter{rulethickness},
      toprulethickness=\framedparameter{rulethickness},
   bottomrulethickness=\framedparameter{rulethickness}]

\setupTABLE  [row] [first] [toprulethickness=1pt]
\setupTABLE  [1]   [first] [bottomrulethickness=2pt]

\stopsetups

\starttext

  \bTABLE [setups=tableborders]
    \bTR\bTD[nc=2] Lorem                               \eTD\eTR
    \bTR\bTD Ipsum  \eTD\bTD Dolor    \eTD\bTD Sit     \eTD\eTR
    \bTR\bTD aaaaaa \eTD\bTD bbbbbbbb \eTD\bTD ccccccc \eTD\eTR
    \bTR\bTD dddd   \eTD\bTD eeeeeeee \eTD\bTD fffff   \eTD\eTR
  \eTABLE

\stoptext

Yes, the setups key was added only to separate the table settings from the content.

That's a simple and neat solution. Thanks a lot. I have the feeling
that sometimes I think much too complicated.

And I really appreciate the response time and the quick help of all
of you on this list.
