table background color in first row

table background color in first row

[Manfred Lotz]

Hi there,


I have s simple table like this:

\starttext

\starttable[|l|l|]
\NC \bf Colheader 1 \NC \bf Colheader 2 \NC \SR \HL 
\NC cell 11 \NC cell 12 \NC \FR
\NC cell 11 \NC cell 12 \NC \LR
\stoptable

\stoptext      


and like to have a light gray background for the heading row. 

I found documentation about \setupTABLE which on the one hand I did not
fully understand how to use and on the other hand I'm not quite sure
how far this is the way it is done nowadays.



-- 
Thanks,
Manfred

The \setupTABLE command for the natural tables environment, you can find
a overview of the different environments on the wiki.

Here is a example for a natural table:

\starttext

\setupTABLE[header][style=bold,background=color,backgroundcolor=gray]

\bTABLE
  \bTABLEhead
    \bTR
      \bTD Colheader 1 \eTD
      \bTD Colheader 2 \eTD
    \eTR
  \eTBALEhead
  \bTABLEbody
    \bTR
      \bTD cell 11 \eTD
      \bTD cell 12 \eTD
    \eTR
    \bTR
      \bTD cell 21 \eTD
      \bTD cell 22 \eTD
    \eTR
  \eTABLEbody
\eTABLE

\stoptext

Thanks for your example which works fine but raises some more questions:

1. Your example creates borders around each cell which I don't want to
have. Any way to get rid of them?


2. It seems to me that \setupTABLE creates a shading for the header for 
all tables in a document?! That is ok. 

However, I'd like to know what would be the variant to have it only for
a single table?


3. How does this \bTABLE stuff compare to the \starttable stuff? Are
these just different methods to create tables which are both in use
these days in context or is one method to be preferred over the other?

Manfred

We come closer. However, I like to have the horizontal line below the
header row.

OK, I found it:

\setupTABLE[row][first][bottomframe=on]

You can disable the border rules with „frame=off“.

\startsetups table:mystyle

  \setupTABLE            [frame=off]

Both are different method to write a table, \starttable/\stoptable is
older than \bTABLE/\eTABLE which use \framed for each table cell and
allows more fancy layouts but is slower than \starttable.

Yep. Just found that I get back the first horizontal line by:

\setupTABLE[row][first][bottomframe=on]

Aaah, ok. Does it mean that \starttable/\stoptable is a simpler way of
writing tables with less possiblities than the \bTABLE/\eTABLE stuff? 

Is also seemed to me that it is not easy to get those shadings using
\starttable/\stoptable. Otherwise you would have given me an example
using \starttable/\stoptable.

Both \BL and \CL work with MkII but in MkIV \BL gives a black rule (rather 
than gray), which \CL gives an error. Hans, any ideas?

For a simple table, you can also use

\startTABLE
  \NC .... \NC  ... \NC \NR
  \NC .... \NC  ... \NC \NR
\stopTABLE

which is wrapper around \bTABLE .. \eTABLE.

The color handling in the old table module is implemented by overloading 
TaBlE code and quite a hack. In mkiv it's easy to add color support but 
then I'd rather remove some of the old commands. In tabulate one can do 
(experimental so not enabled by default):

\ctxlua{nodes.tasks.enableaction("shipouts","nodes.handlers.backgrounds")}

\starttabulate[||p||]
\NC test \NC test \NC test \NC \NR
\NC test \NC[green] \input tufte  \NC[yellow] test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC[blue] test \NC[red] test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC[gray] test \NC \NR
\NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC \NR

So, if there's interest in the \starttable .. \stoptable mechanism (i

some of that code (or just rewrite it from scratch which is probably 
easier).

There is still a use for the old table macros because it’s easier to set small tables (alignment in the preamble versus many \setupTABLE settings), you can set different spacing between rows which is not part of tabulate and you can span cells (also not supported in tabulate).

To make the environment more attractive you should use the tabulate mechanism for background colors (\BC[...] and \VL[...]) and a indent option would be usefull to indent the table in a narrower environment and in itemize.

Perhaps we can add an align key to \startTABLE macro so that we could say

\startTABLE[align={left, right, middle}]
  \NC a \NC b \NC c \NC \NR
  \NC a \NC b \NC c \NC \NR
\stopTABLE

similar to math alignment.

\startTABLE has a optional argument which is passed down to \bTABLE

Can you also add vertical lines and row background colors?

Personally, I do not like the \starttable ... \stoptable macros (the 
patchup with TaBlE macro is too convoluted)  and am happy with the compact 
\startTABLE syntax. But then, I don't use tables too often anyways.
