Tables: Make line-by-line reading sensible. Summarize.

Checkpoint 5.1 [Priority 1] For data tables, identify row and column headers.

Checkpoint 5.2 [Priority 1] For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.

Tips:

• Identify structural groups of rows (THEAD for repeated table headers, TFOOT for repeated table footers, and TBODY for other groups of rows) and groups of columns (COLGROUP and COL).
• Label table elements with the "scope", "headers", and "axis" attributes so that future browsers and assistive technologies will be able to select data from a table by filtering on categories.
• Do not use PRE to create a tabular layout of text -- use the TABLE element so that assistive technologies may recognize that it is a table.
