<p>i'm working with jasper-report, i have this report i want to generate</p>

<p><a href="https://i.stack.imgur.com/PhwWJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PhwWJ.png" alt="my report"></a></p>

<p>i have created a class in java, in which i have a field natureIntervention displayed on the columns, atelier on the rows and numero used for the count in the crosstab</p>

<pre><code>public class ChampEtatMaintenanceParNatureIntervention {

    private String natureIntervention;
    private String atelier; 
    private String numero;


}
</code></pre>

<p>what i'm trying to display is for each row atelier, a list of vehicule types (ex: lourds, legers,....)</p>
