Pivot Table Control
"WebDataRocks Pivot Table is a free JavaScript component for analytics and data visualization.
All you need to start creating reports is to include several scripts to your web page and load your CSV/JSON data. WebDataRocks offers out-of-the-box reporting features such as aggregating, filtering, sorting, drag-and-drop, drill-through, conditional formatting, and more.
The component is built in JavaScript and offers a wrapper for React."
