[NTG-context] More on split TABLES: Numbering Scheme and other things

[Johannes Graumann]

Hello,

I'm using the split-TABLE patch below (send - how can it be different - by
Hans) along with the also appended table definition (to read out XML code).
I have two problems here:
1) as posted earlier, the page just before a split TABLE overflows on the
bottom (see
http://www.idyll.org:8081/JohSite/context/page-overflow-preceeding-a-split-table).
2) I also wonder whether the table numbering scheme this is producing may be
changeable: instead of '1.1a', '1.2b' (currently for two parts of a split
TABLE) the more intuitive '1.1a', '1.1b'

Can anybody give me a helping hand for fixing this?

Thanks, Joh

Table definition:
\defineXMLnested
  [table]
  {
    \defineXMLsave[floattitle]
    \defineXMLsave[caption]
    \defineXMLsave[header]
    \defineXMLsave[body]
    \defineXMLsave[footer]
  }
  {
    \splitfloat
      {
        \expanded{%
          \placetable
            [\XMLpar{table}{location}{here}]
            [\XMLpar{table}{label}{unknown}]
            {\select{figurecaption}{\XMLflush{floattitle}
{{\bf\XMLflush{floattitle}} \XMLflush{caption}}}
            %{\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]}]
          \bTABLEhead\XMLflush{header}\eTABLEhead
          \bTABLEbody\XMLflush{body}\eTABLEbody
          \bTABLEfoot\XMLflush{footer}\eTABLEfoot
        \eTABLE
      }
  }
