What training should be provided to a content author who wants to create multiple tables across the site?

The correct answer is the training on how to use the table plugin that is available in the rich text editor. This is essential for content authors who need an efficient and user-friendly way to create and manage tables within their content. The rich text editor is designed to simplify the content creation process, allowing authors to easily insert tables without needing advanced technical skills or coding knowledge.

Utilizing the table plugin streamlines the workflow by providing a visual and intuitive interface where authors can customize their tables according to the website's design requirements, ensuring consistency across multiple tables used throughout the site.

In contrast, while training on HTML components or custom table components may provide deeper technical capabilities, they require more advanced skills and understanding that may not be necessary for typical content authoring tasks. Furthermore, CSS formatting is important for styling tables, but it does not address the immediate need for creating and inserting tables into site content, thus making it less relevant for this specific scenario.
