Hi,
How can I show multiple tasks on the same row, like here?

Well, they serve the different purpose so it is not that one has advantages over the other one. Scheduler is for "scheduling events" and Gantt for "managing a project." There is an article on Gantt here: https://en.wikipedia.org/wiki/Gantt_chart
So it depends on what do you want to achieve. If it's assigning events (time slots) to resources, whether people, rooms, equipment, etc. then you need Scheduler.
If you want to manage tasks, starting one when it's predecessor finishes, have an info on critical paths, see what happens when one task takes longer or shorter than planned, then Gantt is for you.
