I've started drafting a change proposal for the table DOM Interface. It's still very rough and before I spend more time on it I want to get some feedback. I'm not confident that I'm taking this in the best direction. The goal is make it easier to pull information about cells from tables. Adding methods to retrieve collections of cells that make up columns and clarifying how span attributes affect navigation of the tree could help do this. As it is, assistive technologies receive inconsistent information between browsers (although that might be an artifact of inadequate specification in the HTML4 specification). If the information were available from the DOM, ATs could get more consistent information and applications could also make use of these methods that mirror existing methods for rows. However, the row methods are based on the existence of the tr element and there is only an implied column element. I don't have all of the information about how Javascript libraries do this. I know what we do with WebAnywhere and I've asked some AT developers about their access of tables. As I said, this is rough and I'm not sure if I'm heading in the best direction. Feedback is much appreciated. http://www.w3.org/html/wg/wiki/CellAPIForTable#Edits_to_section_4.9.1_The_table_element Please put this on the agenda for Thursday.
