In this example you will modify the view from Example 2 – Nested Table to show quarterly profit by year and customer segment.
Drag the Customer Segment dimension from the Data window and drop it just to the left of the Profit axis in the view.
The field is added to the Rows shelf and row headers are created. Each header represents a member of the Customer Segment field.
Tableau does not allow you to place a dimension to the right of a measure on either the Rows or Columns shelves.The new dimension divides the view into 16 panes: one for each combination of year and customer segment. This view is a more complex example of a nested table and is often referred to as a small multiples view.
