Sum Columns (beta)

Sum columns provide an easy way to display the "Sum" of a field on a relation.

1SumColumn::make('Total Age of Related Users')
2    ->setDataSource('users','age')
3    ->sortable(),

The "sortable()" callback can accept a callback, or you can use the default behaviour, which calculates the correct field to sort on.
