Modify Default.aspx start page, insert three webpartzones instead one

Question

My Default.aspx in edit mode looks like this:

Is it possible to insert another two webpartzones in "Top" zone?

Ideally I'd want to make this design(becouse I have webparts with such width):

Is it possible and give please any links how can I do it? I watched out-of-box webpartpages, but there is no suitable one. Also I don't think I can set any another page to be a start page..

Answer 1

Put your webpart zones in the following table.

<table width="100%">
    <!-- top row -->
    <tr> 
        <td>
            <!-- top left zone -->
        </td>
            <!-- top middle zone. This is the existing zone in your page. -->
        <td>
        </td>
        <td>
            <!-- top right zone -->
        </td>
    </tr>
    <!-- bottom row -->
    <tr>
        <td colspan="2" rowspan="1">
            <!-- bottom left zone -->
        </td>
        <td>
            <!-- bottom right zone -->
        </td>
    </tr>
</table>

You would have to define two new zones. Copy and paste the top zone. Don't forget to change the Id and name properties of the zones.
