    <h1>Fixed Layout</h1>
    <p>Checks whether fixed layout is implemented properly</p>

    <p>This should be a 100px-wide blue square:</p>
    <p>Width is distributed equally between columns of auto size</p>

    <p>This should be a 100px-wide blue square:</p>
    <p>Width is distributed equally between columns of auto size (even if they are defined by rows other than the first)</p>

    <p>This should be a 100px-wide blue square:</p>
    <p>Widths defined on cells that are not the first row are ignored</p>

    <hr/>
    <p>This should be a 100px-wide blue square:</p>
    <p>The table has to grow to contain the widths defined for its columns</p>

    </x-table>

    <hr/>
    <p>This should be a 100px-wide blue square:</p>
    <p>The first row is based on the visual order, not the dom order</p>
