That may result in a broken table I think. In case of ARIA non-continuous tables is valid example.

From what I can see, the table interface doesn't really support non-contiguous cells... or at least, it wasn't clear that it would. At the very least, non-contiguous cells will break existing versions of NVDA and probably other AT. My recollection is that it was decided that the table interface should be contiguous and attributes should be used to get the *real* numbers. So, using my example, if you have columns 1 and 4 (2 and 3 are a gap), column 4 gets mapped to column 2 in the table interface. If column 1 says it has a span of 2, we have a problem because the spanned column 2 in the table interface maps to ARIA column 4. >> >> Jamie >> >> -- >> James Teh >> Executive Director, NV Access Limited >> Ph +61 7 3149 3306 >> www.nvaccess.org >> Facebook: http://www.facebook.com/NVAccess >> Twitter: @NVAccess >> SIP: jamie@nvaccess.org >>
