With this module you can within a table group and make mathematical operations. You can see in the table below that for some photographers there are several photos. The row is then repeated in each case. You can solve this by grouping, but it disturbs the table structure. This module provides the solution.
You get a new format:
You need to group by a field.
On the same field you can also add the number of items (Tally members)
You get this. The photographer is shown only once together with how many times he / she appears.
The second field we'll just enumerate and sort.
This table shows the grouping within the table. If you jave fields with numbers (eg prices, membership fees, ..) you can also be display them as a sum, average,.. . Even PHP fields can also be used in the calculation!
In the settings you also aggregate on the whole column. Here I make a label first and then I count the number of items.
The table will now show a total at the bottom. (print does not show all 12 items)
