PF4 React-Table - TypeScript followup

In #2360, I noted a couple of additional nice-to-haves:

• It would be better to expose all formatter/transformer props in Table.tsx with our explicitly defined types. Doing so would also require ensuring all formatters and transformers are tested via that interface (as explicit props to Table). https://github.com/patternfly/patternfly-react/pull/2360#issuecomment-517371474

• Ensure that Prettier formatter is applied to React-Table after it is applied in React-Core: #2362

• Determine if we’d like to introduce breaking API changes for the tslint settings different from React-Core: https://github.com/patternfly/patternfly-react/pull/2360#issuecomment-513822602

• Add Cypress/e2e tests

• Consider using an interface for static type analysis of aria props/captions/headers. See comment here.

• Consider rewriting this logic in collapsible.tsx for better type analysis: https://github.com/patternfly/patternfly-react/pull/2360#discussion_r312541336

• Update event types in selectable.tsx: see comment

Thanks @mturley - I’m just now coming across this issue and find it very helpful! I’m working on fixing the selectable transform today - and I’ve had my eye on some of the other stuff mentioned in this issue so let’s keep it open and I’ll work on seeing through the remaining TODO’s. Will tag you for review once I get a PR up.
