Why do tables matter?
NOTE: This item doesn’t mean that you are required to use layout tables when organizing information, but when you are using a table format, you must use the built-in table tools rather than creating the appearance of a table by using tabs or spaces.
Tables ensure you have a reading order that matches the visual layout. They create a structure that screen readers and assistive technology can use to read information in the correct order (left to right then top to bottom).
Tables are sometimes used to organize content. A layout table does not require row or column headers to describe the cell’s content. For example, you could create an agenda with Agenda Item (Introduction), Presenter (Chair), and Time (9 – 9:15) in a layout table.
