--- Comment #4 from b. <newbie-02 at gmx.de> ---
that's ... challenging ... 

esp. while existing filters are not 'clean' but have problems with their
interactions, with compatibility with Excel, storage in different formats,
horizontal autofilters are not implemented, and the question is open how to
control the evaluation of, and the access to, filters in one dimension that are
'off screen' due to transverse filters ... 

unless someone has an important use case for which crossed filters are
absolutely necessary I don't see any chance that a developer will take care of
it ... 

in theory one might attempt a multi-step solution, filtering with 'copy output
to', transposing that area and applying a second filter ... but my system
actually said 'SIGSEV' to such tries, and i've read in other threads that
transposing switches off filtering and similar ... small hope ...
