- [ ] `reactable ` support?
	- [ ] 	Perform a SPIKE early to see how viable it is. More work , but much bigger payout
     - [ ] Spike reactable
              1.  Wire up basic reactivity (simple)
              2. Make reactable-py editable (complex)
                    * research: what would it take to make reactable.js editable?
                   * would involve submitting a PR to glin/reactable
             4. Auto data types -> reactable column
