Since the purpose of `org-dblock-write:columnview' is to capture the
column view, I think the default behavior should be to display *all*
entries, even those which properties are not set - because they are
displayed in the current view.
But maybe a parameter like :skip-empty-row would make sense.
Waiting forward for the org release with the skip-empty-row parameter :)
And also one more interesting feature to have would be this.
Consider
** Task 1
*** Step a
:properties:
:Time_Utilized 10 hours
:end
*** Step b
With Regards
Antano Solar John
:properties:
:Time_Utilized 15 hours
:end
Then in column view it should show
Task Time_Utilikzed
Task1 25
