Auto width and height on table cells

Auto width and height on table cells

[Angel M Alganza via ntg-context]

Hello,

I want some tables to occupy 100% of \textwidth and \textheight and for
all columns to be the same width except one or two that I want to
specify and for all rows to be the same height except for one or two,
that I want to specify as well.. 

For the moment, I'm doing it "manually", calculating column width as

   (\textwidth - width of fixed columns) / # rest of columns

and row height as

   (\textheight - height of fixed rows) / # rest of rows

I'm getting the result that I want, but it's a bit tedious.

Is it possible to have ConTeXt do all those calculations for me?
I haven't been able to figure it out from the manuals and the wiki.

Thank you in advance.

Regards,
Ángel

Thank you very much, that does part of the trick (the column width).
Is there a way to do the same for the row height, please?

I never looked at xtables, since the wiki says they're used for tables
that need to span several pages, which I don't need.

Cheers,
Ángel

They’re also tedious, because you can’t setup rows/columns in advance 
(like \setupTABLE) – or did that change?

You're joking right? SInce when can one not set up something in some 
context subsystem? Why would I make a table mechanism with no presets?

It's just more symbolic than in natural tables (which is better 
performance wise). I'm pretty sure it's mentioned in some manual.

I see! :-)

I didn't see it in the wiki and I thought it didn't exist.

How about the auto row height?  That'd be the only thing I'm missing.

Thanks so much.

we don't have it for the vertical direction ... you can remind me later 
this year (to see if it is doable)

Hi Ángel,

I’m not sure whether I’m totally missing your point, but I think this is
a way that might achieve what you want:

  \starttext
  \showframe
  \startbuffer
  row\currentxtablerow--col\currentxtablecolumn
  \stopbuffer
  \startbuffer[table]
  \startxtable[option={stretch, height}, align={lohi, middle}]
      \startxrow
          \startxcell[width=3cm, option=fixed]\inlinebuffer\stopxcell
          \dorecurse{5}
            {\startxcell\inlinebuffer\stopxcell}
      \stopxrow
      \startxrow
          \startxcell[height=3cm, option=fixed]\inlinebuffer\stopxcell
          \dorecurse{5}
            {\startxcell\inlinebuffer\stopxcell}
      \stopxrow
      \dorecurse{5}
      {\startxrow
          \dorecurse{6}
            {\startxcell\inlinebuffer\stopxcell}
      \stopxrow}
  \stopxtable
  \stopbuffer
  \getbuffer[table]
  \page
  \setuppapersize[A3, landscape]
  \getbuffer[table]
  \stoptext

Just in case it helps,

Pablo

Hi Ángel,

there might be a way to get it, as long as you don’t define height
directly, such as in:

 \starttext
  \showframe
  \startbuffer
  row\currentxtablerow--col\currentxtablecolumn
  \stopbuffer
  \startbuffer[table]
  \startxtable[option={stretch, height}, align={lohi, middle}]
      \startxrow
          \dorecurse{5}
            {\startxcell[width=.115\textwidth]\inlinebuffer\stopxcell}
          \startxcell\inlinebuffer\stopxcell
      \stopxrow
      \startxrow
          \dorecurse{5}
            {\startxcell\inlinebuffer\stopxcell}
          \startxcell[offset=1em]\input zapf\stopxcell
      \stopxrow
      \dorecurse{5}
      {\startxrow
          \dorecurse{6}
            {\startxcell\inlinebuffer\stopxcell}
      \stopxrow}
  \stopxtable
  \stopbuffer
  \getbuffer[table]
  \page
  \setuppapersize[A3, landscape]
  \getbuffer[table]
  \stoptext

Again, just in case it helps,

Pablo

Yes, presets are nice, and I appreciate the better performance, but if I 
can setup stuff like striped tables or some other “advanced” formatting 
without explicite settings within the table, I prefer that.

I can stay with “natural tables” (and “tabulate” for easy cases), but 
the auto-stretching of rows or whole tables _is_ missing.

Unfortunately, this is a situation like in LaTeX: We have a choice of 
table “packages”, but none of them covers my most common use cases.
