                The column header.
            :param aggregate_fn:
                The function used to aggregate the individual values into a single value.
            :param columns:
                List of columns (instances of sqlagg.BaseColumn).

                Function to apply to value before display. Useful for formatting and sorting.

                Unique ID for the column. If not supplied assumed to be slugify(header).

                Indicates if the column should be sortable. If true and no format_fn is provided then
