In your comments on the HTML technique "Using table, tr, and td to present tabular information" you agreed with Michael's suggestion about including an ASCII table as a "counter-example" to show what happens when tabular information is not marked up correctly. You also agreed with Sofia's suggestion to add the scope attribute to the <th> elements identifying column and row headers. This technique has been revised. It has been combined with the technique on using the th element (which no longer exists as an independent technique), and it has been retitled: "Using table markup to present tabular information." The updated technique is available at: http://trace.wisc.edu/wcag_wiki/index.php?title=Using_table_markup_to_pr esent_tabular_information After carefully reviewing the HTML specification, we decided not to add the scope attribute to the th elements in Example 1. The scope attribute is not required by the HTML 4.01 specification. Screen readers can correctly identify column and row headers in simple data tables when only the <th> element is present, and the HTML 4.01 specification describes an algorithm that user agents can use in finding heading information in the absence of scope and headers attributes. Instead of using the scope attribute in this technique, a new HTML technique has been added: "Using the scope attribute to associate header cells and data cells in data tables," available at http://trace.wisc.edu/wcag_wiki/index.php?title=Using_the_scope_attribut e_to_associate_header_cells_and_data_cells_in_data_tables We eexperimented with an example of an ASCII table, but finally decided against using it because (1) it was confusing and (b) it was not consistent with other techniques documents, which try to show correct techniques. We did add a new Failure due to using the HTML pre element to mark up tabular information. Please review the new and revised techniques and let me know if they address your concerns. Thanks so much!
