at the moment, there are only tables for the content, bibliography... and
user-defined tables. Nevertheless there is lack of a table of abbreviations,
because the possible workarounds are not satisfactory (see e.g.
http://www.ooowiki.de/Abk%C3%BCrzungsVerzeichnis): the bibliography is used as a
table of abbreviations, one cannot add a bibliography as a table anymore. When
the user-defined table is used as an table of abbreviations, the entries are not
sorted alphabetically.

A table of abbreviations should
- contain the abbreviation and its explanation
- the ability to have space or dots between them
- sort its entries alphabetically
- the ability to have split the table into two or more columns
- automatically "link" all abbreviations in the text, that have benn recorded
into the table and underlay them in grey, so the author while reading the text
can see which abbreviations are already recorded and which are still missing
