AG Grid
A JavaScript component for large data tables — sorting, filtering, grouping and virtual scrolling across hundreds of thousands of rows.
It solves the problem that a <table> with 100,000 rows kills the browser: only the visible rows are actually rendered into the DOM. Adapters exist for React, Angular and Vue alongside plain JavaScript.
Split into a free community edition and a paid enterprise edition, with the most-requested features — pivoting, server-side row model, Excel export — behind the licence. A good part of why it shows up in corporate apps and rarely in hobby projects.
