TOC fors needtable and Co.

[danwos]

As we know all needtables and co. it would be easy to create a TOC of all tables, flows or co.

Example:

.. toc-needtable::

or

.. toc-needflow::

The output would be a simple list of links to the related table/flow, ...

If the table has no title, the internal ID shall be used as link-text.

Filtering

It would also be good to filter the tables for a specific need. For instance: Show me all needtables which are containing REQ-123.

Example:

... toc-needtable::
    :needs: REQ-123

I'm not sure if a supporting filter-string is needed here. I see currently no use-case, but it would match the way we do filtering currently for all other use cases.

Hint: To know if a need is a part of a needtables, the filter result (need-IDs) must be stored inside the needtables or needflows or ... I'm not sure if this is already the case for all kinds of filter reprensenttions.
