There are a number of ways to define a table:

\startitemize[packed]
\item the \type{\start ... \stoptable} mechanism, based on the work of M. Wichura
\item the \type{\bTABLE ... \eTABLE} mechanism (natural tables)
\item the \type{\start ... \stopxtable} mechanism (extreme tables)
\stopitemize

In the next sections we describe the principles of the three table mechanisms.

\startsection[title=Simple tables]

For defining the table you use:

\shortsetup{starttable}

The definition of a table could look something like this:

\startbuffer
\placetable
  [here]
  [tab:ships]
  {Ships that moored at Hasselt.}
  {\starttable[|c|c|]
  \HL
  \NC \bf Year \NC \bf Number of ships \NC\SR
  \HL
  \NC 1645     \NC 450                 \NC\FR
  \NC 1671     \NC 480                 \NC\MR
  \NC 1676     \NC 500                 \NC\MR
  \NC 1695     \NC 930                 \NC\LR
  \HL
  \stoptable}
\stopbuffer

\typebuffer

This table is typeset as \in{table}[tab:ships].

\getbuffer

Although this table mechanism is still available and supported in \CONTEXT\
it is better to use one of the other mechanisms.

\stopsection

\startsection[title=Natural tables]

The natural table mechanism (\type{\bTABLE ... \eTABLE}) is developed for more
complex tables and has features of the general interface of \CONTEXT.

In the last column a \type{~} is used to simulate a four digit number. The
\type{~} has the width of a digit.

The setup of the table is placed between the square brackets \type{[ ]}. To keep
the data in the table more readable you can set up the table with the \type
{\setupTABLE} command.

With the \type{\setupxtable} it is indicated that the table is allowed to split
at a pagebreak and that the head should contain the content of the \type {\start

\startsection[title=Placing tables]

In all examples you see the command \type{\placetable}. This command has
the same function as \type{placefigure}. It takes care of the vertical
spacing and numbering. The float mechanism is invoked and the table will
end up on the most optimal location in your document.

\shortsetup{placefloat}

You can also set up the layout of tables with:

\shortsetup{setupfloats}

You can set up the numbering and the labels with:

\shortsetup{setupcaptions}

These commands are typed in the set up area of your input file and have a global
effect on all floating blocks.
