How can I generate a report with nested List using Jasper Report (using Spring Boot)

Hello,

I am trying to generate a PDF report using the following entities, but I cannot do it.

public class EmployeeReportData {
 
    private int id;
    private string firstName;
    private string lastName;
    private string department;
 
    private List<WorkedDayAndHours> dayAndHours;
 
    // Getters and Setters
    ...
}
 
public class WorkedDayAndHours {
 
    private Date workedDay;
    private int workedHours;
 
    // Getters and Setters
    ...
}

I would like to create a PDF report using the EmployeeReportData class. Something like the following output:

Is it possible to implement something like this using Spring Boot and Jasper Report? The only issue I have is the List<WorkedDayAndHours> inside the EmployeeReportData class. I do not know how to work with nested lists inside an object.

Normally, I would like to send to jasper a List<EmployeeReportData > which contains a List<WorkedDayAndHours> for each EmployeeReportData record.
