public interface DataColumn<T extends Object> implements DataColumnAggregations<T>
Column with type, name/path and values Base interface only for ValueColumn and FrameColumn
All column extension functions that clash with DataFrame API (such as filter, forEach, map etc.) are defined for this interface, because ColumnGroup doesn't inherit from it
