1. Go to the App overview window and open a new sheet.
2. Enter the Edit mode by clicking on .
3. Create a Table chart.
4. Add a new dimension, and click on the fx button to create it as an expression.

5. Insert the following expression:

=if(Value < 10, dual('less than 10',1),
if(Value < 30, dual('<30',2),
if(Value < 60, dual('<60',3),
dual('above 60',4))))

6. Type Range as a label for the dimension.
7. Add Count(Value) as a measure.
8. The result would be as follows:

9. Change the sorting order of Range dimensions from automatic to Custom, and set sort to numerically.
10. The result would be as follows:

11. As we can see, the sort order is correct now.
