    <h1>Alternating Grid</h1>

    This page is like the Styled Grid page, with the added feature of alternating coloured rows thanks to an EvenOdd class.

    <div class="eg">
        <table t:type="grid" t:source="persons" t:exclude="version"
            t:rowsPerPage="4" t:pagerPosition="top" t:rowClass="prop:evenodd.next">[Grid here]</table>
    </div>
