I think the reasoning behind that they want to support spreadsheets that are loaded by parts on the user request.
If we kept table interface to reflect actual table structure, and put aria row/colcount/index into object attributes, then would it work? I'm not sure what the use case for this was, but regardless, this is potentially going to require a pretty big change to table interfaces. In order to do table navigation, screen readers need to be able to navigate from a given cell to the cell in the next column or the next row, as well as being able to fetch all cells in a given row or column. If the numbering is not sequential, we can't simply increase indexes to do this. No API I know of supports something like this. I guess the table interfaces could just deal with sequential, 0-based coordinates as they always have. We'd then need a way of getting the numbers from aria-*index and aria-*count to report to the user. However, that is extremely obscure and starts to raise questions about why we're doing this in the first place. Jamie On 25/06/2015 9:20 AM, Alexander Surkov wrote: > Hi.
