longtable and tabularx in context

longtable and tabularx in context

[Wybo Dekker]

1: I'm trying to find out how to make long tables (several pages) in
   context. The table manual tells me to add u in the \BeginTable
   command. But if I add that one to \starttable is doesn't recognize
   it.

2: is there a way to expand tables horizontally by expanding (the
   contents of) only certain columns like latex's tabularx?

Use \starttables \stoptables instead. You can also say: 

\splitfloat
  {\placefigure{caption}}
  {whatever to be split} 

or: 

\startbuffer
\startables[preamble]
\stoptables
\stopbuffer

\splitfloat{\placefigure{caption}}{\getbuffer}

Subnumbers are automatically appended. See core-tab.tex (of beta manual)
for more info. 

When nu vertical rules are used, it's better to use \starttabulate ...
\stoptabulate, see latest maps. Tabulations automatically break across
pages, even p entries are split. I'm working on color in tabulations.

When you use \starttabulate ... \stoptabulate, the p entries (there can
be multiple p entries and I will implement width ratios soon) will
divide the available space.

Sure, that worked, partly. However, my table started near the end of
the page, so I added [top] to \placefigure, supposing that context
would decide to start it at top of the next page. Instead, it started
on the *same* page, with the result that the *few* lines that
initially fitted at the end were now (equally few) at the top. With
the result that the floating table became interspersed with (large
amounts of) normal text.

I downloaded the manual (4.4 MB) from the context download page, but
it says nothing about starttabellen or starttabulate. The tran-script
doesn't know about starttabulate. So where do I find this beta manual?

Are footnotes possible in tables? I tried, but a footnote between a
non-floating \starttable appeared on the next page, and one in 
\splitfloat{}{\starttables... didn't appear at all, although its
marker did.

The savest way to handle that is to surround that what should go to the
top of the next page by 

\startpostponing
whatever 
\stoppostponing

tabulate is a composed command the beta manual is at the beta page at
our site

quicky: www.pragma-ade.nl/beta.htm

Footnotes are trouble makers. Their showing up depend on tex's mood, in
the sense that when buried to deep, they (actually any insert) will
never show up. 

%D \start 
%D \startlocalfootnotes[breedte=.3\hsize,n=0]
%D   \plaatstabel
%D     {Some Table}
%D     \plaatsonderelkaar
%D       {\starttabel[|l|r|]
%D        \HL
%D        \VL Nota\voetnoot{Bene} \VL Bene\voetnoot{Nota} \VL\SR
%D        \VL Bene\voetnoot{Nota} \VL Nota\voetnoot{Bene} \VL\SR
%D        \HL
%D        \stoptabel}
%D       {\placelocalfootnotes}
%D \stoplocalfootnotes
%D \stop

This is one way out. With splits ... I never tested this but I fear it
does not work, although \placelocalfootnotes let them show up, so you
can use that one to put them somewhere. 

Like columns, footnotes (inserts actually) are the weakest parts of tex.

That *does* postpone the start of the table to the next page indeed,
but the splitting doesn't work well: the first page of the table shows
a much smaller part of it than is available on the page and leaves the
rest of the page empty. Please try the example below. Sorry for it
being so long, I tried tried to use:

\repeat[80*{just some text before the table}]

but that resulted in an error:
! Extra \fi.

More robust is: 

\dorecurse{80}{whatever}
\dostepwiserecurse{1}{80}{2}{whatever}
\doloop{whatever ..... \exitloop ....}

There is always \recurselevel and when used nested \recursedepth. (When
you want to manipulate: take a look at syst-gen.tex and syst-ext.tex,
they also provide you with quite some \doif.. things).

ah yes, \repeat, that's why recurse is better.

I'll do a bit of testing.  

BTW, I've just finished a new command that can be used for legends to
figures and tables, the better alternative for footnotes I think. More
later.

Perhaps you'd better remove from the manual then?

This is behaviour I like (and I think is to be expected).  You can force a
page break with \page[yes] (? \pagina[ja]).

You can set them below the table with \startlokalevoetnoten (probably
\startlocalfootnotes)  .. \stoplokalevoetnoten.

Try using \starttables .. \stoptables

However, for longer tables you probably are better of using the tabulate
environment. That one works fine.
