When working with large datasets in Grid.js tables, displaying all rows at once can overwhelm both the browser and the user. Pagination is a technique that divides your dataset into smaller, more manageable pages, displaying only a subset of rows at a time. This approach makes your tables faster to load, easier to read, and much more user-friendly. With pagination enabled, users can navigate through pages using intuitive controls, quickly finding the information they need without scrolling through hundreds or thousands of rows. By breaking data into pages, you improve both performance and usability, ensuring that your tables remain responsive and accessible even as your data grows.
