Allow Hiding Columns in Table

[Shejtani]

When adding a column to the table only for the purpose of running a calculation or sorting, there is no option to hide to the user.

In this case, I want to show the the user a calculation of the production order which removes the first 2 digits. The problem is after creating this calculation there is no option to hide the original production order column, which defeats the point of the calculation. There's no reason I should have to display to the user a column, just because I am using it in my query whether thats sorting or calculation.
