On 2008-10-04 bug 94630 was submitted to OOo. It reports "a defect in the way
that user-defined Table Autoformats are saved". Some others including myself
confirmed thwe bug still existing in subsequent releases. The bug is an
important one, because OO, but also LIBO are badly missing table styl
FYI, there is now an "events calendar" on the LibreOffice website. You
will find it in the "About Us" section[1]. For those of you working on
the wiki, you may also find same calendar on the wiki with identical
information[2].
Cheers,
