Is it possible to create dynamic columns when using a!querySelection on a!queryE

Is it possible to create dynamic columns when using a!querySelection on a!queryEntity? Perhaps using apply() to iterate over some list (say of length 3) to generate 3 columns with dynamic field names? If this is possible, could someone help me creating an expression rule with any list of size 2 or 3 to generate dynamic columns with dynamic field names? When I try the attach, I am getting the error: "Expression evaluation error : Syntax error. Details: Expression evaluation error at function a!querySelection parameter 1: Keyword and non-keyword arguments must not be mixed. Used in: apply.." Also, in the attached, I am not using dynamic names for the columns.
