James, The specs on that page relate to the markup for a table... not multiple tables. The headers-id method is suggested for a table in which multiple rows / columns contains header cell data for the data cells of that table. If it is a single row of header cells, all cells can be marked up as TH and the data rows would follow as rows of the same table ... not a separate table. I have seen more than one company resort to the 2-table technique you describe and I had to flag them out and get them fixed. One cannot programatically or semantically relate the contents of one table with another. It is like having a LABEL element in one FORM element and associating it with an INPUT control in another FORM.

I can't find this in the link you referenced. (fyi I would happily recommend this team not to do this if I could back this up with a solid reason - but I cannot come up with one from WCAG2) Regards, James On 4/7/2011 2:24 PM, Sailesh Panchang wrote: James, You need the row / column containing the header cells in the same data table. See http://www.w3.org/TR/REC-html40/struct/tables.html#adef-headers So it fails SC 1.3.1. In any case the headers row and the first table is providing structure for the content that follows and is not mere "presentation". For large tables, implement pagination links ... show next 20 or whatever.

They have their table split into 2 tables in the HTML markup, one for the header row (which has been marked with role=presentation) and one for the data content. They claim they need to do this in order to obtain the visual layout they require. The header cells in the first table have ids associated with them which are then being referenced from the headers attribute of cells in the second table. I can't see any reference in H43 that the cells referenced as a header must be in the same table so it would seem that this would pass 1.3.1 due to meeting H43. Is my interpretation of this correct? If this shouldn't pass H43 I would appreciate the technique being clarified such that this is made more clear. -- Regards, James -- Regards, James James Nurthen | Project Lead, Accessibility Phone: +1 6505066781 | Mobile: +1 4159871918 Oracle Corporate Architecture 500 Oracle Parkway | Redwood City, CA 94065 Oracle is committed to developing practices and products that help protect the environment
