Tables, Grids

Aaron, Jon,

why not use the differences between table and datagrid definitions in

http://www.w3.org/TR/html5/

as basis for the classification scheme in

http://wiki.codetalks.org/wiki/index.php/Complex_Grid_Examples

and to clarify "What is a GRID with respect to a TABLE"?

In this sense (as I understand it) a datagrid is for potentially
editable and potentially hierarchical cells with content (that can be
read-only, too, and yes, a cell may contain multiple values), and tables
are always read-only and for pure layouting (but may contain also
multiple entries per table cell).

Definition from working draft : The datagrid
<http://www.w3.org/TR/html5/interactive-elements.html>  element
represents an interactive representation of tree, list, or tabular data.

if aria role grid is also = datagrid then we don't need aria role
treegrid. Is the author aware of the AT issue you mentioned, Aaron?
