Authors should be able to specify preferred direction and/or order for
sequential navigation, even among things such as tables that would not normally
have a tab order.

Use case: Masahiko is reading a web page, and uses browser commands to move the
text cursor to the next and previous paragraphs. In most cases this works fine
because the suggested reading order is that in which elements occur in the
HTML. However, when Masahiko encounters a table that is designed to be read
down the columns rather than across the rows, this simplistic navigation is
entirely inappropriate. A similar problem occurs when CSS is used to rearrange
blocks of text on the screen.

Recommendation: Allow marking up a table to indicate whether the preferred
reading order is by columns, by rows, both (either being equally valid),
neither (not designed to be read by columns or rows), or left unspecified. This
could be done with a new attribute, such as orientation="columns".
