Comment 286: Expose colspan and rowspan

Status: Answered question

Your comment:
How should I expose colspan="" and rowspan="" on table cells?

Response from the Working Group:
WAI-ARIA is not meant as a replacement for HTML tables. If the author
wishes to have headers that span multiple columns or rows this can be
achieved by overlaying WAI-ARIA on an HTML table or by using
aria-labelledby to have a cell reference its corresponding table. We have
updated the grid design pattern in the WAI-ARIA Best Practices Guide to
reflect this. From a WAI-ARIA perspective, this means there are no specific
requirements and standard HTML processing of these properties would apply.

For WAI-ARIA 2.0, we will reconsider the issue of spanning gridcells.
