Split Table Desperation - again!

Split Table Desperation - again!

[Johannes Graumann]

Hello,

While the recent modifications to the split table mechanisms provided by
Hans help me out with my most annoying monster table using the XML mapping
code below (see
http://www.idyll.org:8081/JohSite/context/p46-50_split_working.pdf/view for
the typeset table; clearly to much whitespace, but everything is typeset
and page boundaries are honored) and several other -smaller- tables in the
same tome (see
http://www.idyll.org:8081/JohSite/context/p45_unsplit_working.pdf/view for
a typeset example), one medium-sized table that clearly should not be split
gets split none the less (see
http://www.idyll.org:8081/JohSite/context/p162-163_unnecessary_split.pdf/view) ...
and I have no idea why.

Puzzled and helpless, Joh

XML mapping code:

% 'table' - table definition
\defineXMLnested
  [table]
  [lines=auto]
  {
    \defineXMLsave[floattitle]
    \defineXMLsave[caption]
    \defineXMLsave[header]
    \defineXMLsave[body]
    \defineXMLsave[footer]
  }
  {
    \splitfloat[lines=\XMLop{lines}]
      {
        \expanded{%
          \placetable
            [\XMLpar{table}{location}{}]
            [\XMLpar{table}{label}{unknown}]
            {\select{caption}{\XMLflush{floattitle}
{{\bf\XMLflush{floattitle}} \XMLflush{caption}}}
        }
      }
      {
        \setupTABLE[row][1][topframe=on]
        \setupTABLE[row][last][bottomframe=on]
\bTABLE[frame=off,split=repeat,splitmethod=b,style={\switchtobodyfont[small]\setupinterlinespace[line=2.8ex]}]

  }
  {\par\eTD}

 some of your rows are quite high and since you want to repeat headers 
... this is how it works

(1) keep at least one row with a repeated header
(2) the same with a repeated footer
(3) when a combination of header/row/footer becomes too high for a page, 
ignore that fact and flush it (else we get a loop)

so, what you see is pretty natural

in your case, i'd try to make the last column wider so that less space 
gets lost and

(i can think of a way to let the text continue on too empty pages; needs 
some braincycles)
