The 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.
Syntax
HTMLCollectionObject = table.tBodies
Example
length(mytable.tBodies);
