Hello,
You can add a hidden column and sort this column and also add a column
containing the values to be displayed.
So you will have something like:
<display:table id="document" name="pageScope.listeDocuments" defaultsort="1"
class="dataTable" decorator="MyDecoratorClass">
<display:column property="dataHidden" title="" class="hidden"
headerClass="hidden" media="html"/>
<display:column property="dataDisplayed" title="My Data" />
</display:table>
Then you can use the MyDecoratorClass to handle this with two methods:
import org.displaytag.decorator.TableDecorator;
public class MyDecoratorClass extends TableDecorator {
public MyDecoratorClass() {
super();
}
// This method is useless
public String getDataHidden() {
MyObject doc = (MyObject) getCurrentRowObject();
return doc.getDataHidden();
}
public String getDataDisplayed () {
MyObject doc = (MyObject) getCurrentRowObject();
String newFormat = "";
// Your code here
return newFormat;
}
}
Hope this helps
David.
