#### Scenario
Cross table viz with _Cell value_ column Set from Property. Property is used to allow user control of Categorical Axes column via a drop-down list.
The table is then to be sorted by selected column.
#### Issue
The sorting column resets to empty every time the Property - i.e., selected column - changes.
#### Expected
The sorting column dynamically refers to the active column that was selected - i.e., Property value.
