Fluid html tree layout help (divs instead of tables)

Question

I need help with a dynamic layout in html. I need it to work as divs but could only set it up with tables.

Basically it's a tree strucutre and as child nodes are added there are child tables created which creates the layout of the nodes I want.

Also does anyone have a clever idea for connecting a line from the parent to the child nodes without using canvas?

Basically it's a mindmap

Here is the html You can see the layout with the html here http://jsfiddle.net/Z6jcD/

<table border="0">
        <tbody>
            <tr>
                <td>
                    <div class="divnodes" contenteditable="true" id="0">
                        <h4 class="marketing-header">Root</h4>
                    </div>
                </td>
