    <title>Creating the Component with a Page Tag</title>
    <para>To create the simplest variant of <property>dataGrid</property> on a page, use the

      <emphasis role="bold">Example:</emphasis>

    <title>Details of Usage</title>
    <para>The component takes a list from a model and outputs it the same way as with <emphasis

        <property>&lt;h:panelGrid&gt;</property>
      </emphasis> for inline data. To define grid properties and styles, use the same definitions as
      for <emphasis role="bold"><property>&lt;h:panelGrid&gt;</property>.</emphasis></para>
    <para>The component allows to:</para>
    <itemizedlist>
      <listitem><para>Use <emphasis>
          <property>&quot;header&quot;</property>
        </emphasis> and <emphasis>

    <para>In order to redefine styles for all <emphasis role="bold">

    </emphasis> components on a page using CSS, it&apos;s enough to create classes with the

    <para>Also it&apos;s possible to change styles of particular <emphasis role="bold"

        ><property>&lt;rich:dataGrid&gt;</property></emphasis> <property>styleClass</property> attributes. An example is placed below:</para>
