Try to follow these steps:

Step 1:Create a calculated field named index and type index()

Step 2: Place the name field and calculated field into the row shelf

Step 3: click on the name and sort it in descending order via the field

Step 4:with integer data type creates a parameter TOP N

Step 5: Create a calculated field called TOP N and enter this formula

if [Index]<=[Top N] THEN "Top N" ELSE IF [Index]>=SIZE()-[Top N] THEN "Bottom n" END

Step 6: Drag top 10 into the filter and select top n and bottom n

Step 7: Drag the new calculation into the rows
