<jsp:root version="1.2" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:display="urn:jsptld:http://displaytag.sf.net">  <jsp:directive.page contentType="text/html; charset=UTF8" />  <jsp:directive.page import="org.displaytag.sample.*" />  <jsp:include page="inc/header.jsp" flush="true" />  <jsp:scriptlet>request.setAttribute( "test", new TestList(10, false) );</jsp:scriptlet>  <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">email@it.com&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>  <jsp:include page="inc/footer.jsp" flush="true" /></jsp:root>
