react-data-grid is a high-performance tabular interface for rendering and manipulating large datasets within a React application. It functions as a virtualized data table and editable spreadsheet component that supports hierarchical data grids with expandable and collapsible row groupings.
The component maintains performance with massive datasets by rendering only the rows and columns currently visible in the viewport. It provides spreadsheet-like data manipulation, including cell editing and the ability to copy, paste, or drag values between cells.
The grid supports advanced layout capabilities such as freezing columns, resizing column widths, and spanning cells across multiple columns. It also includes tools for organizing data through sorting, row selection, and the display of aggregated summary rows.
The project is written in TypeScript.
