Showing subtotals in cross table columns
In a cross table, you can show column subtotals, that is partial summarizations.
About this task
To show subtotals within the cross table columns, the vertical axis (or Row axis) must be structured hierarchically with at least two levels.
In the hierarchy below, subtotals for the month columns are shown on the 'Country' level. The aggregation 'Sum' is used to aggregate the 'Sales' values, and accordingly, the subtotals are also calculated using the 'Sum' aggregation.

If the hierarchy on the vertical axis has more than two levels, you can specify on which levels subtotals should be displayed.
Subtotals are calculated using the same aggregation or expression that is used for the calculation of the cell values. The subtotals are not based on the aggregated values shown in the cross table cells; they are by default based on the underlying data table rows. For example, if 'Average' is used as the aggregation method, the subtotal average of a column takes into account all the data rows on which the cell values are based, and not only the averages shown in the cross table cells. See Displaying totals.
