1	DataTable(ObjectSpecification) Returns an empty DataTable for given domain object type, with all properties as columns, excluding mixed-in ones. (For more control on which columns to include, consider a different constructor.)
2	DataTable(ObjectSpecification, Predicate) Returns an empty DataTable for given domain object type, with all (including mixed-in) associations as columns, that pass given columnFilter . If the filter is null it acts as a pass-through.
3	DataTable(ObjectSpecification, Can) Returns an empty DataTable for given domain object type.
4	forDomainType(Class) Returns an empty DataTable for given domain object type, with all properties as columns, excluding mixed-in ones. (For more control on which columns to include, consider #forDomainType(Class, Predicate) or a constructor that fits.)
5	forDomainType(Class, Predicate) Returns an empty DataTable for given domain object type, with all (including mixed-in) associations as columns, that pass given columnFilter . If the filter is null it acts as a pass-through.
6	getLogicalName() Unique within application scope, can act as an id.
7	getElementCount() Count data rows.
8	withDataElementsFrom(DataTable) Returns a new table, populated from this and the other table.
9	withDataElements(Iterable) Returns a new table instance with the data-elements, which make up the rows of the new table.
10	withDataElementPojos(Iterable) Returns a new table instance with data-elements from given pojos, that are adapted to ManagedObject (s)..
11	withEntities() Returns a new table, populated from the underlying (default) persistence layer.
12	withEntities(Query) Returns a new table, populated from the underlying (default) persistence layer, using given Query to refine the result.
13	exportToBlob(TabularExporter, AccessMode) Typical use-case:
