Highlighting headlines filtered column when using autofilter

[Axel]

Hi,

I'm wondering, if it is possible to highlight all headline cells of a table
(e.g. by a different background colour) which are using a filter (when using
autofilter).

To me that little blue triangle (instead of black) when using autofilters is
somehow just not visible enough.

Any suggestions appreciated.

Cheers, AXEL
