The omission of a createTBody method from HTMLTableElement makes
it rather inconvenient to create a table with both a thead and a tbody
using the table DOM APIs. After creating a thead, you have to manually
create and append the tbody to start putting rows into the body of the
table, so you cannot exclusively use the HTMLTableElement methods to
populate the table. If a createTBody method is added, I'd suggest that
it always create a new tbody rather than ever returning an existing one.
