Hi all - I'd like an opinion on the accessibility of our data tables. I think I've covered everything including: 1. Table caption elements. 2. Proper table structure including th, thead and tbody elements. 3. identifying relationships between columns and cells using scope, id and headers attributes 4. A meaningful table summary attribute. Is there anything I'm missing? http://mit.edu/ocwhq/author/cmstable/100/6columns.html Thanks in advance. -- B.K. DeLong Goodmorning everyone, you have effectively covered all about table's accessibility. Just few tips: -- why using headers element in a simple table such as this? You can just artlessy use a accessible table structure (as you have done) but you can omit headers that are generally used when a table structure is particurarly complicated (th in multi-level/multi-line with colspan, etc...) to vehicle a read by a screen-reader or vocal browser. Now you're developing a table with a linear structure, headers are a plus... -- classes allocated to a row (<tr>) to format a background or other properties aren't perfectly "covered" crossbrowser. If I remember in a right way Netscape don't "feel" these properties, is better use them allocated with a <td> (you can just define by css a general background for all <td> in your contextualized table and a specifical class to applicate alternatively one row yes and one row no using <td> elements). -- and again: when you use a summary attribute it's better if you'll also indicate something about data organization in table below (for example: summary="Table container courses organized by lecture number, topics, key dates and supporting files"). Obviously you have to do it when it's clear it will be an help to a blind person that will probably "hear" your page by a vocal browser or a screen reader. Anyway...well done.
