Hi dev, For Dutch Web Guidelines validity a <th> have to contains scope attribute (scope="col" or scope="row") which means that default wiki tables are invalid currently. See http://www.w3.org/TR/xhtml2/mod-tables.html#non-visual-rendering for example of scope attribute use. I propose to modify XHTML renderer table header cell to do the following: * if a scope is explicitly provided reuse it * if there is no scope: ** if first line or not first column: <th scope="col"> ** if not first line and first column: <th scope="row"> I thing that covers most of the use cases and it will avoid having to set explicitly scope attribute in all our standard pages. WDYT ? -- Thomas Mortagne
