html_begin(table)
        html_begin(table(border(2), align(center)))

This predicate provides an alternative to using the \Command syntax in the html//1 specification. The following two fragments are the same. The preferred solution depends on your preferences as well as whether the specification is generated or entered by the programmer.

table(Rows) -->
        html(table([border(1), align(center), width('80%')],
                   [ \table_header,
                     \table_rows(Rows)
                   ])).

% or

table(Rows) -->
        html_begin(table(border(1), align(center), width('80%'))),
        table_header,
        table_rows,
        html_end(table).
