Lua: change representation of TableHead, TableFoot, and Row values.

The objects now also follow the principle that element attributes are
accessible through the `.attr` field. Rows in `TableHead` and
`TableFoot` are available via the `.rows` field. Row objects have a
`.cells` field, containing the list of table cells.

Closes: #7718
