Progress table shows how much effort remains to complete each User Story /Task in selected Iteration . Thus you clearly see what Tasks are in progress what User Stories have been underestimated and what demands more attention.

To have progress information you should use Time Tracking practice in the following way:

1. Project manager should add User Stories /Task and specify effort.
2. Developer should specify how many hours he spent on each task and how many hours remaining on his opinion. This should be done every day.

Having this information, TargetProcess draws daily burn down chart and shows detailed progress table.
