Re: Bug: Messy results when using "table" in head and multi-page "tables" in text

[Carsten Fechtmann <fecht@zarm-technik.de>]

Dear Wolfgang,

I tried that too already, but unfortunately I run into the same problem:
That is, if I use the natural tables in the header, I can't use them  
for multi-page tables in the text, as again the results ain't pretty,  
to say the least.

Here the ConTeXt to show what happens in that case
(and using your suggestion for the page-head with natural tables)

\setuppagenumbering[location=]
\setupheadertexts[\setups{pagehead}][][\setups{pagehead}][]
\startsetups[pagehead]
\bTABLE[option=stretch,strut=no,offset=.5em]
  \bTR
    \bTD[align={right,lohi},width=4cm] left \eTD
    \bTD[align={middle,lohi},width=6cm] middle \eTD
    \bTD[align={left,lohi},width=4cm] right \eTD
  \eTR
\eTABLE
\stopsetups

\starttext

\bTABLE[split=repeat,option=stretch,strut=no,offset=.5em]
\bTABLEhead[rulethickness=1pt]
   \bTR
      \bTH[align={middle,lohi},width=6cm] head \eTH
   \eTR
\eTABLEhead
\bTABLEbody%
%\dorecurse{1}{	% works
\dorecurse{10}{	% works NOT
   \bTR
     \bTD
	{\input knuth \par}
     \eTD
   \eTR
}
\eTABLEbody
\bTABLEfoot
   \bTR
     \bTH footer  \eTH
   \eTR
\eTABLEfoot
\eTABLE

\stoptext

The thing is, I rather tell the users of this page-layout NOT to use  
the \starttables ... \stoptables for multi-page tables, but rely on  
the natural tables for those (which work nicely, even though I  
_really_ would like to have a dedicated footer for each page here and  
not just one for the last page! Which by the way is something one  
doesn't need a dedicated command for, as one could _always_ just place  
that part at the end of the body part, as that will be then at the end  
of the table, i.e. the right place, no matter how many pages the table  
has.)
However, given, that \starttables ... \stoptables doesn't give me the  
correct footer in my case anyway, I rather have one type of table that  
is quite a bit easier for me and my colleagues to use and adapt for  
the multi-page tables, i.e. the 'natural' ones, and therefore keep  
using table in the header.

But yes, thanks for the suggestion, unfortunately, TABLE seems to rely  
on the same sort of buffer / storage / whatever mechanism, to do it's  
multi-page magic....

And that just doesn't work with having the same table-type in the  
header, too.
(This is probably also true in case of the footer...)

Overall, things do work, as long as one does use the other type of  
table or tables / TABLE in either header or text, but it works NOT  
when you use the same in both...

Not quite sure, what's the reason for that or (and more importantly)  
what can be done about it

With best regards
Carsten

P.S.: What is interesting is that on the last pages of a multi-page  
table things do become sorted out again in either case and everything  
looks more or less as it should (i.e. like in the single-page table)
