Example for Checkpoint
5.2 - For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.

For "complex" tables, i.e. where tables have structural divisions beyond those implicit in the rows and columns, use appropriate markup to identify those divisions.

Example: A travel expenses worksheet. While the following data table appears simple enough visually, it would be difficult to understand if read by some of today's screen-readers. A good way to approximate what some screen-reader users will hear is to hold a ruler to the table, and read straight across the screen. Then, move the ruler down until the next line of characters is displayed. Read straight across. Acter a while, pick a data cell at random and, without looking at the column or row title, try and remember what headers describe that data point. The larger and more complex the table, the harder it would be to remember the row and column relationships.
