The table currently supports filtering, but to see how many filters are active per column, one needs to click it and see which filter options are checked.

Instead, we could display the filter count in the top right corner relative to the chevron icon so that it's visible without clicking the chevron.

Implementation note: If there are > 9 filters active, display 9+ instead of the actual number to prevent too big count numbers and related spacing problems.
