Enhanced Table Sandbox Demo: https://codesandbox.io/s/n5wy74w8vl
edit: Looking at other of the demos, it seems that this is affecting all sandbox demos currently. So far I've checked all the Table demos and a Paper demo. If I run across one that it unaffected I'll update this, but it seems it's something about the base setup that is breaking.
Sandbox demo loads without errors
Upon opening sandbox link, the following error is displayed:
TypeError
Cannot read property '1' of null

Happy to help to debug, but I couldn't see an obvious way to investigate what's causing the error.

This looks like a Codesandbox bug. I can open the same demo on StackBlitz: https://stackblitz.com/edit/epqw4i?file=demo.js cc @CompuIves
I had this problem with the Multiple Select component
@carpben All the codesandbox demos seem to be broken, use StackBlitz for now.

Looking at it now!
@CompuIves Awesome, if that can help, I believe it's very recent.
Deploying a fix now, I'm sorry that this just happened after your release!
I will add this sandbox and some other material-ui sandboxes to our automated test integrations so this won't happen again.
Fix should be live within 20 minutes.
Okay, fix is live now. It may require a second refresh to see the changes because of service workers, but for most people it should work on first try!
@CompuIves Awesome support, thank you
