iGddZy)c(eZdZdZdZdZdZdZy) Computationa Computations produce a new column by performing a calculation on each row. Computations are applied with :class:`.TableSet.compute`. When implementing a custom computation, ensure that the values returned by :meth:`.Computation.run` are of the type specified by :meth:`.Computation.get_computed_data_type`. This can be ensured by using the :meth:`.DataType.cast` method. See :class:`.Formula` for an example. c.|jjS)zq String representation of this column.
