You can achieve this by using a Decorator.
Your jsp:
<display:table id="myTable" decorator="my.decorator.MyDecorator">
<display:column property="date" titleKey="header.date"/>
<display:column property="id" titleKey="header.id"/>
<display:column property="name" titleKey="header.name"/>
<display:column property="adjust" titleKey="header.adjust"/>
<%-- notice no mention of the comment column --%>
</display:table>
and implement the TableDecorator class:
package my.decorator;
import org.displaytag.decorator.TableDecorator;
public class MyDecorator extends TableDecorator {
/**
* Adds a comment row to the table.
*/
public String finishRow() {
StringBuffer footer = new StringBuffer();
MyObject curr = (MyObject)this.getCurrentRowObject();
footer.append("<tr><td> </td><td colspan\"3\">");
footer.append(myObject.getComment());
footer.append("</td></tr>");
return footer.toString();
}
}
Ed!
