Display fields from two different objects in a single column of a datatable?

Hello, so I try to create a datatable component that displays tasks and events of a contact in a single table. 
task1   ActivityDate
task2   ActivityDate
event1   ActivityDate
task3   ActivityDate
event2   ActivityDate
event3   ActivityDate

For now I created a code that shows both tasks and events but in two seperated areas, but I really do not know what approach I should take to combine the results of these two. Maybe you could help me with this topic. So my Controller now is like that:
public class ApexActivityWrapper {

	public static wrapper method1 (){
        string userId = UserInfo.getUserId();
    List<Task> getTask = [SELECT Subject, ActivityDate FROM Task WHERE OwnerId=:userId ORDER BY ActivityDate];
    List<Event> getEvent =	[SELECT Subject, ActivityDate FROM Event WHERE OwnerId=:userId ORDER BY ActivityDate];
           wrapper wrp = new wrapper();
    	wrp.taskList = new List<Task>(getTask);
    	wrp.eventList = new List<Event>(getEvent);
    return wrp;

	public class wrapper{
    		public List<Task> taskList ;
    		public List <Event> eventList;

one way is to create a wrapper class with a similar set of fields from the event and task objects. Iterate through a list of events and tasks and add the items to the wrapper.
