    Individual GridThemes are defined using the &lt;Theme&gt; tag.
    Formatting instructions are issued using an &lt;Apply&gt; tag.
    Attributes of the &lt;Apply&gt; tag are interpreted as properties of a TableCell object.
    Without specifying conditions or a row type, the instruction is applied to all table cells.<br />
    <br />
    <pre>&lt;theme id="Apply1" title="Sample: Apply tag"&gt;
    &lt;apply backColor="#CCCCCC" foreColor="blue"&nbsp;
    &nbsp; &nbsp; &nbsp; &nbsp;horizontalAlign="center"
           /&gt;<br />&lt;/theme&gt;
    </pre>
