Can you confirm this hasn't affected the other list views, they're using the same table component.

i just took a look at list view, they look normal. can you review and test? @nytai

[nytai]

Code looks fine 😄 . I have a bunch of other stuff running at the moment and it's hard to switch over to superset, but I'll test once i'm done with my current setup

[adam-stasiak]

Tested it is ok. I found an issue with scrolling on Safari but not related to this change. I will raise it in another issue :)
