In several tables cells are not created when they should be blank. Example: [http://en.wikipedia.org/w/index.php?title=Dwain_Chambers&oldid=383112406#Competition_record Dwain Chambers]. Is it an accessibility issue? Does it makes the table confusion for screen reader users? Regards, [[User:Dodoïste|Dodoïste]] ([[User talk:Dodoïste|talk]]) 20:18, 13 September 2010 (UTC)
:It's actually a UAAG issue. See [http://www.w3.org/TR/html401/struct/tables.html#h-11.2.4.3 Calculating the number of columns in a table]:
:* "... if the TABLE element contains no COLGROUP or COL elements, user agents should base the number of columns on what is required by the rows. The number of columns is equal to the number of columns required by the row with the most columns, including cells that span multiple columns. For any row that has fewer than this number of columns, the end of that row should be padded with empty cells."
:So user agents should supply empty cells (rather than failing to provide anything). Agents that conform to h-11.2.4.3 will not cause any accessibility issues specific to disabled users; but may have accessibility implications for all users of text-only agents (since they generally do not distinguish between empty and row-spanned cells). --[[User:RexxS|RexxS]] ([[User talk:RexxS|talk]]) 21:58, 13 September 2010 (UTC)
