[JamesWTruher]

Summary of the new feature / enhancement

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
System Idle Process              0 Services                   0          8 K
System                           4 Services                   0      8,240 K

The output should not include the object with "==*" in all the fields

Proposed technical implementation details (optional)

those separators are really important for determining where the columns are, so it shouldn't happen before the columns are determined.
