flat-table
|
|
~~~~~~~~~~
|
|
|
|
Implementation of the ``flat-table`` reST-directive.
|
|
|
|
:copyright: Copyright (C) 2016 Markus Heiser
|
|
:license: GPL Version 2, June 1991 see linux/COPYING for details.
|
|
|
|
The ``flat-table`` (:py:class:`FlatTable`) is a double-stage list similar to
|
|
the ``list-table`` with some additional features:
|
|
|
|
* *column-span*: with the role ``cspan`` a cell can be extended through
|
|
additional columns
|
|
|
|
* *row-span*: with the role ``rspan`` a cell can be extended through
|
|
additional rows
|
|
|
|
* *auto span* 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 automaticly 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 autospann missing cells, insert missing cells
|
|
|
|
roles:
|
|
|
|
* cspan: [int] additionale columns (*morecols*)
|
|
* rspan: [int] additionale rows (*morerows*)
