Great!

How does this compare to react-virtualized (https://github.com/bvaughn/react-virtualized)? Does it handle tables (rendered with table elements and not div)? Does it support column virtual scrolling?

In terms of performance and size it's much better. Though it's more of a base component and you can virtualize any sort of scrollable element that you can render, vertical or horizontal.
