Specify an HTML table's <tbody> element as a region in Marionette for Backbone.js

Problem

Using a Backbone.Marrionette.Layout to present some tabular data. The <tbody> portion of the table is a Backbone.Marionette.Region that is meant to display a Backbone.Marionette.CollectionView.

I can not figure out how to do this using Marionette's "Regions" without messing up the table display by inserting an extra HTML element inside the <tbody> element.

Example Code

The Layout looks like this:

Backbone.Marionette.Layout.extend({
    template:...
    regions:{
        list_region: '#list-region'
    }
    onRender:function(){
        var collection = new TheCollection()
        var collectionView = new TheCollectionView({
            collection: collection
        })
        // PROBLEM: The region seems to needs its own HTML element,
        //   and the CollectionView also seems to need its on HTML
        //   element, but as far as I can see, there is only room 
        //    for one element: <tbody>?
        this.list_region.show(collectionView);
});

The template for the Layout comprises the entire table:

<table>

    <tbody id='list-region'>

    </tbody>

    <tfoot id='footer-region'>
        Some other stuff goes here that is not a collection, so I was able 
        to make the View's 'tagName' property 'tr', which worked fine.
    </tfoot>

</table>

Any suggestions?
