I understand that you could sort fields in Expression editor using sort function
but I think it is bit less user friendly since you have to modify the expression everytime you change the sort field.
So, I thought it would be easier if sorting using header field is avaialbe , like in below site.
Sort Table by Clicking the Headers
However, looking through the document sorting seems to be not supported in pure table function.
Is there any way to do sorting using header field ? Or is it already in line for feature request ?
