The ajax debug toolbar uses tables. But i think it's not only me who uses some kind of css-reset script e.g. from Foundation:

table {
    background: none repeat scroll 0 0 #fff;
    border: 1px solid #dcdcdc;
    margin-bottom: 1.25rem;
    table-layout: fixed;
    width: 100%;
}

So that will garble the output:

Better to refactor to keep the div style like the other toolbar elements?
