PivotTable is used to 'rotate' a source table such that it is summarized on the values of some
column.
Utility methods to aid in the construction of complex queries on tables
Allows user to set column types.
A tabular data structure like a table in a relational database, but not formally implementing the
relational algebra

relation.
