Wow, I'm pretty happy to see this project :D.

• Would [Table] Add the possibility of custom element type #7765 help for the virtual scrolling?

• Looks like you have built a Pagination component [Table] Add support for pagination #7746. Interested in porting the source code into Material-UI or having a demo in our documentation website?

Also, I'm wondering if we couldn't add a link to this project in the table.md page for people intersted in more complex use cases. What do you think?

Thanks for the feedback :) Sure you can add the link to our project anywhere you think it might be helpful. We'll consider the possibility of porting the Pagination component to the material-ui package if somebody can help us with it. We'll also check out your hint regarding the virtual scrolling. Thanks.
