There's no way to disable column resizing within the <rich:extendedDataTable> tag itself. However, with a little CSS to hide the element that enables resizing, you can accomplish what you're trying to do:

<style type="text/css">
    .extdt-hsep {
        display: none;
    }
</style>

Note that this will only prevent the user from resizing columns. It will not stop the automatic ratio-based resizing that happens when you resize the grid itself (e.g.: when you resize the window and the grid has 100% width).
