Considerations for Customizing the Task List in Lightning Experience
In the task list, you can customize the display and order of fields for individual tasks using task compact layouts. However, even if you remove certain fields from a layout, they remain in the task list because they contain critical task information. For example, suppose that you remove the status and due date fields from a compact layout. The task checkbox and the due date still appear on tasks in the list. The remaining fields visible in the list reflect the fields you include in the compact layout.
