Document that [] is required for \starttabulatehead in MkIV. Email by Wolfgang Schuster 2018-11-12.
< [[Tables Overview]] | [[Table]] >
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]]).
This is especially suited if you want to have paragraphs in one (or more) of the tabulate columns.=Summary=
{{cmd|starttabulate}} is a versatile table environment.It supports ''paragraphs'' in cells, ''vertical rules'' (forthose typographically less demanding jobs&nbsp;…), and''colorization'' of those rules, the background 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 corresponding 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|]\HL\NC {\bf format} \NC {\bf meaning}\NC Mk \NC\NR\HL\NC c \NC centered \NC\NR\NC l \NC left aligned \NC\NR\NC r \NC right aligned \NC\NR\NC w(1cm) \NC one line, fixed width \NC\NR\NC p(2cm) \NC paragraph, lines broken to fixed width \NC\NR\NC cg(.) \NC align on a character \NC\NR\HL\stoptabulate</context>|} * <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 thecurrent page-width. For example: if you want the previous tabletake up all the width and having the second column taking threequarters of the space, change the formatting characters{{cmd|starttabulate}} to:

Context supports different categories of rules that can be
configured 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 between
ordinary rows of the table body and will prevent page breaks
&ndash; no way you’d end up with a rogue hairline desecrating
the bottom of your page’s text area.
{|cellpadding="10" style="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.
|}
 
Additionally, there is an option <tt>rulecolor</tt> for
{{cmd|setuptabulate}} that allows for those rules to be tinted.
 
<texcode>
\setuptabulate[rulecolor=red]
 
\starttabulate[|r|c|l|]
\FL
\NC first row \NC test \NC test \NC\NR
\ML
\NC rows in \NC test \NC test \NC\NR
\NC between \NC test \NC test \NC\NR
\LL
\NC last row \NC test \NC test \NC\NR
\BL
\stoptabulate
</texcode>
 
Other types can be discovered in the source
([[source:tabl-tbl.mkiv|tabl-tbl.mkiv]]).
 
===Vertical Rules===
 
The <cmd>VL</cmd> command serves as a replacement for <cmd>NC</cmd>
to mark a cell border wherever a vertical rule may be desired (if
they are to be desired at all from a typographical point of
view).
 
<texcode>
\starttabulate[||||]
\NC test \VL test \VL test \VL\NR
\VL test \NC test \VL test \VL\NR
\VL test \VL test \NC test \VL\NR
\VL test \VL test \VL test \NC\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>
* HL ===Colorizing Backgrounds & Text===Backgrounds and text can be colorized either on column basis orindividually 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 horizontal applied to the text itself - in other words, the "foreground color."|}These are to complement the normal table layout expression (thefirst argument to {{cmd|starttabulate}.Thus, in order to colorize a four column table with the initiallayout <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, canreplace the ordinary <cmd>NC</cmd>, allowing individual cells tobe 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 tothe ''first'' row of a paragraph cell. Any other cell will comeout colorless. If you need to color an entire multi-linecell,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 forvertical 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 baselinedistance you can use this code: <texcode>\unprotect\appendtoks \blank[halfline]\to \t_tabl_tabulate_every_after_row\protect</texcode> --> <context mode=mkiv source=yes>\starttabulate \NC one \NC two \NC\NR \NC two \NC three \NC\NR \TB[halfline] \NC four \NC five \NC\NR \TB[line] \NC four \NC five \NC\NR \TB[1cm] \NC eight \NC nine \NC\NR \stoptabulate</context> =Using math mode= If you want to display numerics, you can simply use <cmd>NN</cmd> for a new column (or new cell)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|l|]\HL* \NN 10e-3 \NN 10e+3 \NR is new row\HL\stoptabulate</texcode>
The sample looks like this:instead of
<contexttexcode>
\starttabulate[|l|l|]
\HL
\NC format $10\cdot 10^{-3}$ \NC meaning $10 \NCcdot 10^3$ \NR\HL\stoptabulate</texcode> although both variants do work. If you always need math in one column, consider math mode columns: <texcode>\starttabulate[|m|m|]
\HL
\NC c 10e-3 \NC centered \NC\NR\NC l \NC left aligned \NC\NR\NC r \NC right aligned \NC\NR\NC w(1cm) \NC one line, fixed width \NC\NR\NC p(2cm) \NC paragraph, lines broken to fixed width \NC\NR% You can leave out the \NC before 10e+3 \NR
\HL
\stoptabulate
</texcode>
 
 
=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 penalties which force a twoline split whereas the snapping mechanism prevents this. As a result two lines are typeset on top of each other. The solution is to add the following statement to the preamble:
<texcode>\tabulatesplitlinemode \plustwo</texcode>
 
The following code provided by Wolfgang Schuster demonstrates the problem: Compile with and without the line <tt>\tabulatesplitlinemode\plustwo</tt>
 
<texcode>
\tabulatesplitlinemode \plustwo
\starttabulate[|p|]
\NC
one \par
\blank[penalty:10000]
two \par
\blank[penalty:10000]
three
\NC\NR
\stoptabulate
</texcode>
 
The same is true if you use {{cmd|framed}} or something that uses it internally, like [[Widgets]], within Tabulate.
