qdoc3: Don't put a \table in a \value

In qdoc, the \value command is meant to document a single value of an
enum. e.g.

\value TypeOfService Text describing the type of service. It runs until
the next \value or a blank line.

Although it doesn't say you can't build a \table in the \value text,
it doesn't work. For now, the fix is to remove the \table from the
\value text and make the table separate from the enum \value list and
let the description of the \table refer to the value that it belongs
to.
