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

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

[Carsten Fechtmann]

Dear ConTeXt experts,

I have setup a page layout where I use "table" in the page-head for  
formatting quite a bit of stuff. (The example below is just a simple  
as can be basic idea, to show the overall effect)
Now - as I can't prevent later users of this layout environment - to  
not use \starttables ... \stoptables I naturally would like for this  
to work in the text region as well.
This works fine and as advertised (well mostly, see below) as long as  
the table does not spill over to the next page. In which case, things  
start to look very messy, indeed.

 From my (simple) point of view it looks like ConTeXt gets confused  
about which format to use for which table and tries to do them all at  
the same place or something.

Any chance to get this fixed ?

Thanks in advance
Carsten

P.S.: There is an additional bug (also concerning the single page  
version and not related to having a "table" in the pagehead), which  
puts in an extra (empty) gap in between the end of the tablebody and  
the tablefoot when the tablefoot starts with \HL (and there is no \HL  
at the end of tablebody).
Things work when putting the \HL at the end of the tablebody, but then  
no \HL will be put on top of the foot for any intermediate pages of  
the table, which is certainly not what one would usually want in this  
case.


Anyway, here a simple version of this to demonstrate the effect(s)

\setuppagenumbering[location=]
\setupheadertexts[\setups{pagehead}][][\setups{pagehead}][]
\startsetups[pagehead]
\SetTableToWidth{\makeupwidth}
\starttable[|p(40mm)|p(60mm)|p(40mm)|]
\HL
\VL \leftaligned{left} \VL \midaligned{middle} \VL  
\rightaligned{right} \VL\SR
\HL
\stoptable
\stopsetups

\starttext

\start
\SetTableToWidth{\makeupwidth}
\setuptables[split=repeat]
\starttablehead
\HL
\VL Head \VL\SR
\HL
\stoptablehead
\starttabletail
\HL	% This results in an additional bug,
	% i.e. an extra / unwanted gap
\VL   Foot \VL\SR
\HL
\stoptabletail
\starttables[|p(.95\textwidth)|]
\VL \input knuth \VL\FR
%\dorecurse{1}{\VL \input tufte \VL\MR}
\dorecurse{10}{\VL \input tufte \VL\MR}
\VL \input knuth \VL\LR
% \HL 	% putting \HL here does not introduce
	% that unwanted gap ...?!?
\stoptables
\stop

\stoptext

Use the following setup for the header, it use natural tables.

\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

I have no solution for this.

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

[Carsten Fechtmann]

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)

next solution, framed:

\startsetups[pagehead]
\setupframed[strut=no,offset=.5em,height=1cm]
\dontleavehmode
\framed[align={right,lohi},width=\dimexpr(\textwidth/7)*2+\linewidth

This is the wishlist from us users since a few years.

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

[Carsten Fechtmann]

Dear Wolfgang,

first, I _really_ appreciate your effort. Unfortunately, for me  
\framed is not likely to do the job, as the header is a bit more  
complicated in real-life (I told you so ;-).
And yes, actually, using framed had been my very first approach as the  
original LaTeX layout had been using \begin{picture} ...  
\end{picture}. Therefore, I thought at that time going the \framed  
route should do the trick....

Here is an (still simplified) example why I don't think it would

\setuplayout[%
   width=160mm,
   topspace=10mm,
   header=35mm,
   headerdistance=5mm,
]
\setuppagenumbering[location=]
\setupheadertexts[\setups{pagehead}][][\setups{pagehead}][]

\startsetups[pagehead]
   \setupframed[offset=3pt]
   \setupcombinations[distance=-\linewidth,width=160mm,align=no]
   \dontleavehmode
   \startcombination[3]
   {\framed[align={right,lohi},height=27mm,width=35mm\relax]
     { LOGO  } }
   {\framed[align={right,lohi},width=35mm\relax]
     {left} }
   {\framed[align={middle,lohi},height=27mm,width=80mm\relax]
     {titel } }
   {\framed[align={middle,lohi},width=80mm\relax]
     {middle} }
   {\framed[align={right,lohi},height=27mm,width=45mm\relax]
     {other stuff}  }
   {\framed[align={middle,lohi},width=45mm\relax]
     {Page:~\pagenumber\ of \lastpage}}
   \stopcombination
\stopsetups

\starttext
\input knuth
\stoptext

Again, as I am still new to ConTeXt, there might be a way to get rid  
of the spaces between the frames, somehow. But I still would -- in the  
real version -- also need some extra alignments within some cells and  
in short this gets just more ugly with every further step.

I also had been thinking about going the "metafun" route. However, I  
do need a simple, out of the box solution that even the greenest TeX  
newbie could use and setup on all sorts of OS's ...
In short, I fear that is also not going to be a choice at the moment.

Open to suggestions
Yours
	Carsten

Hi Carsten,

I have another solution for you, you could use a layer to place the header
on every page.

\setuppagenumbering[location=]

\startsetups[pagehead]
\bTABLE[offset=3pt]
  \bTR
    \bTD[align={right,lohi},height=27mm,width=35mm] LOGO \eTD
   \bTD[align={middle,lohi},height=27mm,width=80mm] titel \eTD
   \bTD[align={right,lohi},height=27mm,width=45mm] other stuff \eTD
  \eTR
  \bTR
    \bTD[align={right,lohi},width=35mm] left \eTD
    \bTD[align={middle,lohi},width=80mm] middle \eTD
    \bTD[align={middle,lohi},width=45mm] Page:~\pagenumber\ of \lastpage \eTD

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

[Peter Rolf]

Hi Carsten,

I'm not quite sure if this is a help (was just playing around with it 
while watching snooker).

I had to clear|redefine the table head|tail in the page head (or is this 
intended?). There are still some unwanted vertical offsets above|below 
the page head. If you use a hbox instead of a vbox for the page head you 
will see the difference on the last page. So this space is introduced by 
the splitted table somehow. Don't ask me for details ;)

Best wishes,

Peter

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

[Carsten Fechtmann]

Dear Peter and Wolfgang,

sorry for taking a bit longer to come back to you and your suggestions  
here.
But I got some strange results and did some further testing and trying  
on all this.
What got me a bit, was/is that your suggestion below works as is, but  
fails with only slightly more complicated tables. Specifically, in the  
case where there is more than one row.
Furthermore, one can't leave out
\starttablehead\stoptablehead
\starttabletail\stoptabletail
even in the case of just using the "table" environment, instead of  
"tables". Don't ask me why.
In short, Peter, while your solution works as is, I would not  
recommend it for anything more complicated then the example below, and  
in that case one is probably better of using the framed solution from  
Wolfgang. Either that, or using the earlier idea with overlay from  
Wolfgang

This works just fine. THANKS A LOT for this. :-D

I had been playing around with overlays at the very beginning of my  
ConTeXt tries and had soon come to the conclusion to do some more  
basic stuff first and ... somehow never got back around to it up till  
now.
However, it is the way to go here, as it does indeed separate -  
somehow - the inner workings of the table structures enough so that  
ConTeXt is no longer getting confused about them anymore.
In short, this works as advertised.

Cheers
Carsten

P.S.: Still would be nice to have this issue fixed.
P.S.S.: It does not help with the second bug within the "tables"  
environment, i.e. the starting \HL line in the "tabletail" introducing  
an extra and unwanted! gap in the table.
Ugly workaround for me at the moment is drawing a not completely line  
by using \framed[width=broad,topframe=on]{} above the text.
While slightly better than either no line or a line with said gap, it  
is not exactly what I had in mind here, either...
