Checkboxes

In plain words: Adding checkboxes and radio buttons to a custom DataTable in Lightning Web Components (LWC) allows users to select individual rows, toggle boolean column values, or make single-select choices directly inside a structured table. By configuring native datatable properties or custom column attributes, you can turn a static table into an interactive grid. Displaying data in a tabular format is a standard requirement in Salesforce applications. Often, users need to interact with table rows—such as selecting records for batch approval, toggling active states, or picking a single record from a list. The standard <lightning-datatable> component supports built-in row selection checkboxes out of the box, but rendering custom boolean toggles or radio selections requires specific column type attributes.
