Sometimes you want to typeset paragraphs in a specific formatted way. This is
done with:

\shortsetup{starttabulate}

The tabulation mechanism is closely related to the table mechanism. You can use
the tabulation mechanism in cases you want to typeset complete paragraphs within
a cell. The tabulation mechanism also works fine at a page break.

\startbuffer
\starttabulate[|w(1.5cm)B|p(6.0cm)|p|]
\NC 1252
    \NC Hasselt obtains its city charter from bishop Hendrik
        van Vianden.
    \NC Hendrik van Vianden was pressed by other towns not
        to agree with the charter. It took Hasselt a long
        period of time to convince the Bishop. After
        supporting the Bishop in a small war against the
        Drents, the charter was released. \NC\NR
\NC 1350
    \NC Hasselt joins the Hanzepact to protect their
        international trade.
    \NC The Hanzepact was of great importance for merchants
        in Hasselt. In those days trading goods were taxed
        at every city, highway or rivercrossing. After
        joining the Hanzepact duty free routes all over
        Europe became available to Hasselt. However
        important the Hanzepact was, Hasselt always stayed a
        minor member of the pact. \NC\NR

A tabulate definition could look like this:

\typebuffer

In this case the first column is \unit{1.5 centi meter} wide and is typeset bold
(\type{B}). The second column has a width of \unit{6 centi meter} and is typeset
like a paragraph. The remaining horizontal space is used up by the last
paragraph.

The example is typeset like this:

\getbuffer

The tabulation entries are placed between the \type{\start ... \stoptabulate}
pair. Between the bracket pair your can specify the tabulate format with the
column separators \type{|} and the format keys (see \in {table}
[tab:tabularformattingkeys]).

Another example of paragraph formatting could look like this.

\startbuffer
\definetabulate[ChemPar][|l|p|l|]

\startChemPar
\NC Limekilns
    \NC Hasselt has its own limekilns. These were build in 1504
        and produced quick lime up to 1956. Nowadays they are a
        tourist attraction.
    \NC \inlinechemical{CaCO_3,GIVES,CaO,+,CO_2} \NC\NR
\stopChemPar
\stopbuffer

\typebuffer

And it would come out like this:

\getbuffer

In \in{chapter}[chemical] your can find some more information on chemistry
and \CONTEXT.

Here we also introduced the command to define our own paragraph layout.

\shortsetup{definetabulate}

and we also have:

\shortsetup{setuptabulate}

\stopchapter

\stopcomponent
