For very complex tables, a table ALT tag can be used to add extra information for screen readers (see Quickstart Guides above for details). When inserting a data table, make sure the first row/column is marked as a header and includes a description of the type of data used in each row or column.See details in the Quickstart Guides above. For long documents, insert or generate a table of contents based on Heading 1, Heading 2, Heading 3 styles.Ensure that all documents use semantic heading styles.When inserting images or charts, be sure to add ALT tags or a description of the image for screenreaders.Some content on this site based on material from Michigan State Web Accessibility and used with their permission.
