A slightly more clean way of doing this and to prevent unnecessary DOM traversal, you can simply traversal down the hierarchy of the views themselves:

```javascript
// tbody elements
this.children.each(function(body) {
    // trow element
    body.children.each(function(row) {
        // td/th elements
        row.children.each(function(cell) {

        });
    });
});
```
