Tables
======
.. sidebar:: Nested tables
Nested tables are ugly! Not all builder support nested tables, don't use
them!
ASCII-art tables like :ref:`reST simple table` and :ref:`reST grid table` might
be comfortable for readers of the text-files, but they have huge disadvantages
in the creation and modifying. First, they are hard to edit. Think about
adding a row or a column to a ASCII-art table or adding a paragraph in a cell,
it is a nightmare on big tables.
.. sidebar:: List tables
For meaningful patch and diff use :ref:`reST flat table`.
Second the diff of modifying ASCII-art tables is not meaningful, e.g. widening a
cell generates a diff in which also changes are included, which are only
ascribable to the ASCII-art. Anyway, if you prefer ASCII-art for any reason,
here are some helpers:
* `Emacs Table Mode`_
* `Online Tables Generator`_
.. _reST simple table:
Simple tables
-------------
:duref:`Simple tables <simple-tables>` allow *colspan* but not *rowspan*. If
your table need some metadata (e.g. a title) you need to add the ``.. table::
directive`` :dudir:`(ref) <table>` in front and place the table in its body:
.. code:: reST

.. _reST flat table:
flat-table
----------
The ``flat-table`` is a further developed variant of the :ref:`list tables
<linuxdoc:list-table-directives>`. It is a double-stage list similar to the
:dudir:`list-table` with some additional features:
column-span: ``cspan``
with the role ``cspan`` a cell can be extended through additional columns
row-span: ``rspan``
with the role ``rspan`` a cell can be extended through additional rows
auto-span:
spans rightmost cell of a table row over the missing cells on the right side
of that table-row. With Option ``:fill-cells:`` this behavior can changed
from *auto span* to *auto fill*, which automatically inserts (empty) cells
instead of spanning the last cell.
options:
:header-rows: [int] count of header rows
:stub-columns: [int] count of stub columns
:widths: [[int] [int] ... ] widths of columns
:fill-cells: instead of auto-span missing cells, insert missing cells
roles:
:cspan: [int] additional columns (*morecols*)
:rspan: [int] additional rows (*morerows*)
The example below shows how to use this markup. The first level of the staged
list is the *table-row*. In the *table-row* there is only one markup allowed,
the list of the cells in this *table-row*. Exception are *comments* ( ``..`` )
and *targets* (e.g. a ref to :ref:`row 2 of table's body <row body 2>`).
