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[<display:column property="email" />]]></code></li> <li><code><![CDATA[<display:column title="email">email@it.com</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>
