For form inputs inside a data table (e.g. for indicating number of items to be ordered), I have used the input title attribute rather than a hidden explicitly associated label to indicate the purpose of the input. This seems to work fine with an accessibly marked up data table. As you read the table with a screen reader the col and row THs can be associated with the cell containing the input. And, when you move from input to input filling in the form elements, the title attribute is presented. Of course, the title attribute has to be meaningful.

Both aria-labelledby and the use of title appear to function fine with keyboard and screen reader. We recommended using the aria technique unless backward compatibility was an issue. One point of consideration is whether your "data table" is really a data table in this context, or if it is actually a presentation table that is using the col and row headers as labels. That may seem like a fine distinction, but housing inputs in a data table can potentially affect the behaviour of some assistive technologies.

The information is presented as a data table to show and edit the values of each record, so the column headers act as labels for each field, and row headers identify each record. For example, imagine that you have a chess shop: Columns: Piece, color, material, unit price Rows: King, Queen, Rook, Knight, Bishop, Pawn Thus, we need to construct the "label" for each field combining both row and column headers "Queen color", "Knight unit price", etc. We have tested aria-labelledby to do this, and it seems to work fine with all the screen readers and platforms that we have tested (JAWS & NVDA w/ IE & FF, VoiceOver w/ Safari). We have also seen that this technique has been submitted to the WCAG WG [1]. However, I cannot find it in the Techniques document, so I don't know if there is a reason to avoiding it. What do you think? Would it be acceptable to use aria-labelledby as the only way to label a form control? Thanks in advance, Ramón.
