HTMLTableElement.tBodies read-only property returns a live
HTMLCollection of the table bodies.
Although the property is read-only, the returned object is live and allows the modification of its content.
The collection returned includes implicit
<tbody> elements. E.g.
<table> <tr> <td>cell one</td> </tr> </table>
The HTML DOM generated from the above HTML will have a
<tbody> element even though the tags are not included in the source HTML.
