Caption in grouped table showing incorrect numbers

The new table component seems to have issues with the captions, if rows are grouped.
(1) the numbers shown beginning with the 2nd group don't make sense and seem to still refer to the first group.
(2) the line break and spaces are ignored

(3) It would be great to have grouping options also for the caption and indicators etc. (I might want to show there a maximum instead of a sum)

(4) Date fields are not possible to show in the group header, only count distincts are allowed. However, a Maximum or a Minimum (for the earliest or latest date) would totally make sense
