Let’s give an option to our end user to sort the report output as per their selected fields. Not by report design.
To keep the sorting feature more rich and relevant, let’s go through with the following steps:
Step1. Create a new parameter (enable Allow Multiple Values) and list out all the field names under Available Values property of the parameter. Specify field names under Label as you want to show to your end user and keep the value same as in your dataset field name. Keep the order of the fields in which you want to sort the report output.

Step2. Now open property window of your table’s group and select Sorting. Refer Image-2
Step3. Now put following expression under Sort by and also set required Order for each of fields that are available in your parameter list. Refer Image-3
