> 27 Marking HTML table cells for WAI > 27.3 Using the id/headers method to identify table cells > 27.3.1 Choosing an id/headers level
If you decide to use the id
/headers
method, you can choose from three levels:
First see if you can use groups to adequately identify cells; if grouping header cells does not give you enough resolution, consider span attributes; if span attributes do not suffice, use row and column IDs to provide the maximum amount of identification for each cell.
If you need to identify cells by virtual or conceptual
properties, or by disjoint groupings of header cells, you might want
to apply the axis
attribute also, using one of the
table markup methods described in §26.2.3 Assigning table-cell attribute values with dedicated
formats or §26.2.4 Assigning table-cell attribute values with custom markers.
