      Current Result

      it takes over 2 mins

      Expected Result

      reduced to several seconds

      Debug Information

      1. DependencyTableEx.getEvaluatedDependents() consumes most of the time
      2. Notifying content change when hiding columns takes lots of time, normally it's unnecessary for most cases. Since hidden columns don't change their content. Maybe we should notify only for specific cases e.g. when enabling this option: a chart that doesn't show data from hidden rows/columns
