HighTable is a React component created by Kenny Daniel for Hyperparam. It displays large datasets efficiently using virtual scroll. From 2024, I had the opportunity to become co-maintainer of the library, and I contributed to it by adding features like keyboard navigation, sort, rows selection, etc.

In 2026, I published a blog post (on my blog and on Hyperparam’s blog) about the work I did to allow scrolling through billions of rows in a table, while maintaining good performance and accessibility. The feature was added to HighTable, and it required such amount of research and effort that we decided to write about it in details.
