Document that [] is required for \starttabulatehead in MkIV. Email by Wolfgang Schuster 2018-11-12.
< [[Tables Overview]] | [[Table]] >
== Basic commands ==
Rather simple tabulating. You ''need'' the bars in the formatting field of <cmd>starttabulate</cmd>! '''If you want vertical lines, you need another table mode''' (see [[Tables]]).=Summary=
This {{cmd|starttabulate}} is especially suited if you want to have a versatile table environment.It supports ''paragraphs '' in one cells, ''vertical rules'' (or moreforthose typographically less demanding jobs&nbsp;…) , and''colorization'' of those rules, the tabulate columnsbackground of fields as wellas the text itself.
'''Warning''': When you want to use tables with macros use {{cmd|starttable}} and \stoptable. {{cmd|starttabulate}} and \stoptabulate does not work correctly with macros. =Basic commands= The sample describes control sequence {{cmd|starttabulate|[#1]}} takes a layoutstring as optional argument.As is common with tables in TeX-based typesetting, this string(in its basic variant) consists primarily of the ''bar''character (“<tt>|</tt>”) as delimiter for columns,and of the letters <tt>c</tt>, <tt>l</tt>, as well as <tt>r</tt>,denoting the ''alignment'' within cells of this row. For instance consider a two-column table: if any text in thefirst column should be right aligned (''real''[[right and left|<tt>flushright</tt>]]) and the second columnleft aligned, the formatting characterscorresponding format string would be<tt>|l|r|</tt>.''NB'':those bars, as stated above, denote cell limits only&ndash; ''not'' vertical lines. <!-- - wtf this listing was full of <tab> chars‽ Was this supposed - to be a bad pun on *tabulate*? - - No, I formatted it readably in my text editor. --HR-->{| ! width="55%"| ! width="10%"| ! width="35%"| |- | <texcode>\starttabulate[|r|l|lB|]\HL\NC {\bf format} \NC {\bf meaning} \NC Mk \NC\NR\HL\NC c \NC centered \NC \NC\NR\NC l \NC left aligned \NC \NC\NR\NC r \NC right aligned \NC \NC\NR\NC w(1cm) \NC one line, fixed width \NC \NC\NR\NC p(2cm) \NC paragraph, lines broken to fixed width \NC \NC\NR\NC cg(.) \NC align on a character \NC IV: cg{.} \NC\NR\NC m \NC math mode \NC IV only \NC\NR\NC b \NC before e.g. b{\star} \NC IV only \NC\NR\NC a \NC after, e.g. a{\percent} \NC IV only \NC\NR\HL\stoptabulate</texcode>||<context>\setuppapersize[A5]\starttabulate[|r|l|lB|]

* <cmd>HL</cmd> draws a horizontal rule,
* <cmd>NC</cmd> marks a new column (or new cell),
* <cmd>NN</cmd> marks a new math column/cell (see below),
* <cmd>NR</cmd> starts a new row,
* <cmd>NB</cmd> starts a new row as a block (avoids page breaking inside of a block, to keep some lines together<!--; available since beta of 2011-12-21-->);
* <cmd>TB</cmd> (= "Table Blank") adds some vertical space between rows -- see an example bellow,
* <cmd>VL</cmd> (instead of <cmd>NC</cmd>) draws a vertical rule -- for more info see below.
 
When using fixed width, you can use values relative to the
current page-width. For example: if you want the previous table
take up all the width and having the second column taking three
quarters of the space, change the {{cmd|starttabulate}} to:
<texcode>
\starttabulate[|rw(.25\textwidth)|lw(.75\textwidth)|]
</texcode>
(Mistake: This doesn’t account for the width of the column distance!)

This is a very long text, longer than the width of the table.
It must be long enough to flow to the next line to see the effect.

Context supports different categories of rules that can beconfigured individually in order to discern various applications.Their behaviour accounts for the designated use, e.g.<tt>\ML</tt> (mid rules) are intended to be deployed betweenordinary rows of the table body and will prevent page breaks&ndash; no way you’d end up with a rogue hairline desecratingthe bottom of your page’s text area.{|cellpadding="10" style= Column Spans ="border:2px solid #addeff"! style="background:#addeff;" | Type !! Description|-|<tt>\HL</tt> || standard horizontal rule;|-|<tt>\FL</tt> || first rule;|-|<tt>\ML</tt> || mid rule;|-|<tt>\LL</tt> || bottom rule;|-|<tt>\LL</tt> and <tt>\TL</tt> || bottom rule;|-|<tt>\BL</tt> || last rule.|}
Tabulate has no support Additionally, there is an option <tt>rulecolor</tt> for column spans but you could add this function yourself{{cmd|setuptabulate}} that allows for those rules to be tinted.
The code to do this depends on the tabulate setting and you have to know what<texcode>content what column setting you need.\setuptabulate[rulecolor=red]

To span columns Other types can be discovered in cells with <code>l</code>, <code>r</code> or <code>c</code>the sourceyou could use <code>\span\omit\span\omit\span\omit</code> for each cell([[source:tabl-tbl.mkiv|tabl-tbl.mkiv]]).
You could prevent these values you could them in a macro and use it with===Vertical Rules=== The <codecmd>\use{2}VL</codecmd> or command serves as a replacement for <codecmd>\TWONC</codecmd> in the tabulate environmentto mark a cell border wherever a vertical rule may be desired (ifthey are to be desired at all from a typographical point ofview).
<texcode>
\defstarttabulate[||||] \NC test \VL test \VL test \VL\NR \VL test \NC test \VL test \VL\NR \VL test \VL test \NC test \tabulateuse#1%VL\NR { \dorecurse{VL test \numexpr2*#1-1VL test \relax}{VL test \spanNC\omit}}NR \stoptabulate</texcode>
==Coloring==
 
The following elements can be colorized: rules, cell backgrounds,
and, obviously, common text.
 
===Colorizing Rules===
 
For ''horizontal rules'' see above.
 
For ''vertical rules'', <cmd>VL</cmd> takes a defined color as an
optional argument.
 
<texcode>
\starttabulate[|r|c|l|]
\VL test \VL[red] red rule \VL test \VL \NR
\VL test \VL[green] green rule \VL test \VL \NR
\VL test \VL[blue] blue rule \VL test \VL \NR
\stoptabulate
</texcode>
 
===Colorizing Backgrounds & Text===
Backgrounds and text can be colorized either on column basis or
individually by cell.
 
There are five color-specific control sequences:
{|
|<cmd>CR</cmd> || color is applied to the background of the text and the remaining space on the right.
|-
|<cmd>CC</cmd> || color is applied to the background of the text only.
|-
|<cmd>CM</cmd> || color is applied to the background of the text and the remaining space on both sides.
|-
|<cmd>CL</cmd> || color is applied to the background of the text and the remaining space on the left.
|-
|<cmd>CT</cmd> || color is applied to the text itself - in other words, the "foreground color."
|}
These are to complement the normal table layout expression (the
first argument to {{cmd|starttabulate}.
Thus, in order to colorize a four column table with the initial
layout <tt>|c|c|c|c|</tt> it will have to be modified as follows:
<texcode>
\starttabulate[|CR{red}c|CC{yellow}c|CM{green}c|CL{blue}c|]
\NC test \NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC test \NC \NR
\NC test \NC test \NC test \NC test \NC \NR
\stoptabulate
</texcode>
 
Those control sequences, if applied within the table body, can
replace the ordinary <cmd>NC</cmd>, allowing individual cells to
be colorized.
<texcode>
\starttabulate[|c|c|c|c|c|c|]
\NC g \NC l \NC i \NC d \NC e \NC r \NC \NR
\NC g \NC l \NC i \CM[blue] d \NC e \NC r \NC \NR
\NC g \NC l \NC i \NC d \CM[blue] e \NC r \NC \NR
\NC g \NC l \CM[blue] i \CM[blue] d \CM[blue] e \NC r \NC \NR
\NC g \NC l \NC i \NC d \NC e \NC r \NC \NR
\stoptabulate
</texcode>
 
'''caveat emptor'''! The background coloring does apply only to
the ''first'' row of a paragraph cell. Any other cell will come
out colorless. If you need to color an entire multi-line cell,
you will need to switch to another
[[Tables Overview|tabulation variant]].
 
===Colorizing Cell Text===
''Normal text'' inside cells gets its color via the
[[Color|standard coloring commands]], or by the
shorter variant described above.
 
<texcode>
\starttabulate[|r|c|l|]
\NC test \NC {\colored[red] test} \NC test \NC\NR
\NC test \NC {\colored[green] test} \NC test \NC\NR
\NC test \NC {\colored[blue] test} \NC test \NC\NR
\NC test \NC {\colored[cyan] test} \NC test \NC\NR
\stoptabulate
</texcode>
 
== Vertical Distance Between Rows ==
 
<!--
There does not seem to be an official interface for
vertical skips.
Manually placed <code>\blank</code>s are
<code>\unskipped</code> on purpose.
However, as expected there is a token list
<code>\t_tabl_tabulate_every_after_row</code> that is
placed after a line is finished.
So, in order to get a vertical spacing of half a baseline
distance you can use this code:
 
<texcode>
\unprotect
\appendtoks
\letblank[halfline]\to \t_tabl_tabulate_every_after_row\protect</texcode> --> <context mode=mkiv source=yes>\starttabulate \useNC one \tabulateuseNC two \NC\NR \defineTABLEshorthandsNC two \NC three \NC\NR \to TB[halfline] \NC four \NC five \NC\NR \TB[line] \NC four \NC five \NC\NR \TB[1cm] \NC eight \NC nine \NC\NR \everytabulatestoptabulate</context>
\starttext=Using math mode=
If you want to display numerics, you can simply use <cmd>NN</cmd> for a new column instead of <cmd>NC</cmd>. This command works similar to the [http://www.pragma-ade.com/general/magazines/mag-0003.pdf digit-module]. Therefore you can also abbreviate: <texcode>\starttabulate[|l|Br|l|l|]\NC a \NC b HL\NC c NN 10e-3 \NC d NN 10e+3 \NR\NC 1 \NC 2 \TWO \NC 4 \NRHL
\stoptabulate
</texcode>
 
instead of
<texcode>\stoptextstarttabulate[|l|l|]\HL\NC $10\cdot 10^{-3}$ \NC $10 \cdot 10^3$ \NR\HL\stoptabulate
</texcode>
=== Paragraph columns ===although both variants do work.
For spanned columns in cells with paragraphs If you always need a different implementation.math in one column, consider math mode columns:
To use this macro you have to take care about a few things:<texcode>\starttabulate[|m|m|]\HL\NC 10e-3 \NC 10e+3 \NR\HL\stoptabulate</texcode>
* You have =Itemization or framed objects inside a tabulation= <!--(added by Willi Egger 04-08-2011, edited by Hraban 2015-10-06)--> The following issue is related to MkIV: When using an itemization inside a tabulation where one uses also the {{cmd|head}} command, there occurs a snapping problem. This is related to set penalties which force a twoline split whereas the snapping mechanism prevents this. As a width for result two lines are typeset on top of each cellother. The solution is to add the following statement to the preamble:<texcode>\tabulatesplitlinemode \plustwo</texcode> * The format for following code provided by Wolfgang Schuster demonstrates the spanned column is fixed problem: Compile with and you have to change it in without the macroline <tt>\tabulatesplitlinemode\plustwo</tt>
