A Data Grid is a component used in software applications to display and manage large sets of data in a tabular format. It allows users to view, edit, and manipulate data efficiently, often providing features like sorting, filtering, and pagination. Data Grids are commonly used in web applications and can be integrated with various frameworks and libraries. These grids can be customized to fit specific needs, supporting different data types and formats. They often work with back-end systems, such as databases, to retrieve and update information dynamically. Popular libraries for implementing Data Grids include React Table and AG Grid.
