The table provides extra information to a screen reader user and impacts the order in which they navigate through the content. The biggest problem is when a developer uses a table in order to format a page. Frequently when a developer eliminates tables for “accessibility,” they simply put all the information into linear form,potentially making it tedious to navigate. Users can sort horizontally and vertically to find what they want without having to go through every piece of information. Tables also make it easier to sort through a lot of information more quickly. They provide information about relationships, simply explaining how one piece of information is oriented with respect to another, and how sets of information relate to one another. Tables are just as valuable to someone who is blind as to someone who is sighted. Writing all of this information out in a single line of text would make it much more challenging to access, understand, and recognize patterns and relationships. For example, month and year horizontally along the top and climate information such as highest/lowest temperature, precipitation, and humidity vertically along the left. Some data often times fits best into a table, rather than a paragraph. A list of books can be organized vertically by information such as the title, author (s), editor, publication year, or ISBN and horizontally by the book.
For example, the dates on a calendar are organized horizontally by day of the week and vertically by week of the month. Tables display pieces of information that have some sort of relationship. Even more important though, is a web developer using tables appropriately and designing them correctly.
