1- I could not find a request for Subtotals in feature requests.
2- However, there are questions about how subtotals can be done in the Questions section. Even @Aleksi as previously prepared a sample application for Subtotals.
3- Praveen stated that the improvement on Filters will be implemented soon.
4- I request it to be evaluated together with its filter feature and subtotal feature. If possible, I would like you to add banded rows feature along with filter feature to the application to increase readability.
There are 3 different features in the picture below.
1- Filter feature (This has already been requested and will be available )(Add filter capability on top of the columns).
2- Banded Rows feature
3- Subtotals Feature
