Description
Is your feature request related to a problem? Please describe.
Currently there's no tree visualisation for a pivot table (like in Excel). It's a really neat layout that allows lazy and partial exploration of the data.
Describe the solution you'd like
A data table capable of (partially and fully) collapsing and expanding the data as if it was a tree.
Describe alternatives you've considered
Using pandas, active_cell and dcc.Store (to keep track of odd/even clicks) to pivot/un-pivot and filter data on cell click.
Additional context

Research direction
No files, tests, or entry points are named. Start by locating the existing Data Table and pivot-table implementation, then determine how grouped rows or columns are represented and rendered. Done means the table supports both partial and full collapsing and expanding in a tree-like layout, as described in the issue.
