doc-rst: flat-table directive - initial implementation
Implements the reST flat-table directive.
The ``flat-table`` 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)
list tables
The *list tables* formats are double stage lists. Compared to the
ASCII-art they migth be less comfortable for readers of the
text-files. Their advantage is, that they are easy to create/modify
and that the diff of a modification is much more meaningfull, because
it is limited to the modified content.
The initial implementation was taken from the sphkerneldoc project [1]

+list tables
+-----------
+
+We recommend the use of *list table* formats. The *list table* formats are
+double-stage lists. Compared to the ASCII-art they might not be as
+comfortable for
+readers of the text files. Their advantage is that they are easy to
+create or modify and that the diff of a modification is much more meaningful,
+because it is limited to the modified content.
+
+The ``flat-table`` 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 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-spanning 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*. Exceptions are *comments* ( ``..`` )
+and *targets* (e.g. a ref to ``:ref:`last row <last row>``` / :ref:`last row
+<last row>`).
