The output of "kubectl get taskruns" was really confusing

Expected Behavior

When I execute kubectl get taskruns, I expect to get a clear and helpful information.
These information could tell me the status of taskruns at least.

A simple one should look like this:

NAME      AGE      STATUS
test-run   1h         Running

A better one like this:

NAME      AGE      STEPS      STATUS    REASON
test-run   1h     1/3          Running         -

Actual Behavior

NAME      TYPE        STATUS   STARTTIME   COMPLETIONTIME
test-run   Succeeded   False        1d                1d

This output seems like the "Pod condition" ? The "False/True" things. I think it's not make sense to display these information here.

Additional Info

I also check the Argo's "workflow" the same thing with "taskrun", the output like this:

kubectl -n kubeflow get workflow
NAME                         AGE
calculation-pipeline-drllv   15d

But in the output of kubectl get taskruns -o yaml, I get this:

  phase: Succeeded
  startedAt: 2019-03-19T06:37:23Z

So I suggest add phase to the status section of taskrun and display as STATUS in the output of kubectl get taskruns if needed.
