We'll take a look at some of the options for Table Calculations shortly. Based on the options, you can compute Table Calculations in one of the two following ways:

• Relative: The Table Calculation will be computed relative to the layout of the table. They might move across or down the table. Rearranging dimensions in a way that changes the table will change the Table Calculation results. As we'll see, the key for relative Table Calculations is scope and direction. When you set a Table Calculation to use a relative computation, it will continue to use the same relative scope and direction, even if you rearrange the view.
• Fixed: The Table Calculation will be computed using one or more dimensions. Rearranging those dimensions will not change the computation of the Table Calculation. Here the scope and direction remain fixed to one or more dimensions, no matter where they are moved within the view. When we talk about fixed Table Calculations, we'll focus on the concepts of partitioning and addressing.

You can see these concepts in the user interface. The following is the Table Calculation editor that appears when you select Edit Table Calculation from the menu of a Table Calculation field:

We'll explore the options and terms in more detail, but for now, notice the options that relate to specifying a Table Calculation that is computed relative to Rows and Columns, and options that specify a Table Calculation that is computed fixed to certain dimensions in the view.
