Boosting Web Table Accessibility: A Deep Dive into Tab Roving

This article tackles the challenges of focus management in web tables, especially for keyboard users where traditional tab navigation is inefficient. The author introduces a technique called "Tab Roving," which uses arrow keys to navigate between table cells, treating the entire table as a single focusable element. This significantly improves the user experience for keyboard users. The article details the implementation principles, including the use of the `tabindex` attribute, focus tracking, and a code example in React, and discusses other application scenarios such as mega menus and custom numerical input fields.
