Welcome! To confirm, are you looking for row grouping capabilities, and being able to expand to show the underlying data?
The enhanced table plugin is an open source project built by someone in the community. It might be worth raising a feature request on the GitHub project itself to see if there is interest, or even consider contributing the change yourself.
This expansion doesn't look to be possible in Kibana as far as I can see, even in more recent versions. There are some alternatives in this thread. For this precise functionality you could try to build a Kibana plugin leveraging a grid with grouping capabilities, but as I've not tried that myself it would be a guess from me.
Hope that helps!
