  <h2>Columns</h2>

  <display:table name="test">
    <display:column property="id" title="ID" />
    <display:column property="name" />
    <display:column property="email" />
    <display:column property="status" />
    <display:column property="description" title="Comments" />
  </display:table>


  <p>This example starts to show you how to use the table tag. You point the table tag at a datasource (a List), then
  define a number of columns with properties that map to accessor methods (getXXX) for each object in the List.</p>

  <p>Note that you have one column tag for every column that you want to appear in the table. And, the column specifies
  what property is shown in that particular row.</p>

  <p>You can define the content of a column by adding a <code>property</code> attribute to the column tag or adding a
  content to the tag.</p>

  <ul>
    <li><code><![CDATA[&lt;display:column property="email" />]]></code></li>
    <li><code><![CDATA[&lt;display:column title="email">[e-mail]&lt;/display:column>]]></code></li>
  </ul>

  <p>There are two ways to define the content of a column. Of course, in the tag body you can use scriptlets or other
  custom tags. Using the <code>property</code> attribute to define the content of a column is usually faster and works
  better with sorting. If you add a <code>property</code> attribute the tag body is ignored.</p>

  <p>The <code>property</code> attribute specifies what <code>getXXX</code> method is called on each item in the list.
  So for the second column, <code>getName</code> is called. By default the property name is used as the header of the
  column unless you explicitly give the column a title.</p>
