Might this be something that the accessibility committees can discuss? The W.A.I., PDF/UA, and EPUB?

I agree - I have seen situations where we need headings within data tables because there can be large amounts of data in table cells that is indeed tabular data. Ideally the user agents and AT should be smart enough to figure out a heading structure within a cell might be specific to that cell rather than relative to the document as a whole -- but unfortunately this has never been well adopted.

Agree with Karen's and others' comments.



But I have found legitimate needs for subheads within tables used for statistical data, such as a government agency's table I reviewed today. These are data tables, not layout tables.



I don't think table subheads like the samples below should use the same tags as H1 to H6 used for navigation in the main document. Instead, I'd like the WAI committee to consider specific table subhead tags that will notify the user that they're entering a new section of content in the table, and maybe even let the user navigate within the table by these table subheads.



A small snippet of a sample table like this is below.

It has two subcategories for Social Security and Major Health Care Programs, along with their subtotals.

I don't know what to call these items, maybe table section headers would work. Their purpose is to signal the reader that they are entering a new section of data within the table.



One technique we use with this type of table is to write a table summary that describes the table's structure, such as 'This table contains several subsections of data with individual subtotals for each subsection: Social Security, Major Health Care Programs,- etc.
