Thanks @afzalsayed96 I'm going to ask our designers to review the loading state. They may ask for some edits to the UX. Issue #2402 is for the data-table component that I plan on taking a slightly different direction on.

[afzalsayed96]

Thanks for the update @chasestarr . It completely makes to have the design reviewed.

[chasestarr]

Design likes the changes. Thank you. A couple of requests, but once addressed this will be ready to merge

[afzalsayed96]

Thanks for the feedback. Much cleaner now 👍

Looks good other than a comment! Thanks for contributing!

jest fails due to a snapshots being out of sync. Can you please run yarn test -u and commit the result?

[afzalsayed96]

I was facing some issues running yarn test -u on windows. Specifically when it calls yarn validate:examples command. Running node ./scripts/validate-examples.js manually worked. (Use cross-spawn?)

Also I updated scripts/validate-examples.js to be platform independent when splitting by new lines separator.

@afzalsayed96 can you contribute your changes too, maybe in a new PR that would solve the issues you faced on windows?
