how to mark task progress by %

Hi team, 

I saw the screenshot above mentioning percentage, is there any way to mark the completed percentage of each task? And I know once we marked status, it will only show right after the task name, is there anyway to mark it in the gantt chart to make it obvious?

Thanks,
