task status not available for display/sorting

For each tasks I can change the status in the task form from Not started yet or in Process to Delayed or Waiting for another process. I am particularly interest in the “Waiting” option because it helps me with follow-up of open issues. 

But in the task table view this field is not accessible. Neither display nor sorting/grouping is possible. No smart folder either. How can I enable this?

Thank you for your help.  

Hello Jan,
unfortunately it is not possible to view the task status in the table view.

Best regards,
Olivia
