Hi Matt,
A table element can have a 'sortable' attribute which designates you can
sort on columns. A table header cell <th> can have a 'sorted' attribute to
tell you that the rows are sortable on this column and may tell you that
the table is sorted by that column. The 'sorted' attribute should have the
value 'reverse' when the table is sorted on the column and in reverse
order. I assume you can add JavaScript to sort on a column and the this is
all allowed as a sortable table. If you can do sorting on a table, how is
it different from a grid?
I am also confused on the valid state/values for the 'sorted' attribute. Is
it:
<th> // not a sortable column
<th sorted> // means you may sort on this column, but the table isn't
sorted on this column
<th sorted='' > // means you may sort on this column and the table is
sorted on this column (normal sort order)
<th sorted='reversed' > // means you may sort on this column and the
table is sorted on this column (reverse sort order)
When I read the spec I cannot tell if 2 and 3 are distinct states and both
valid.
