		DataTables has the ability to read data from a variety of complex data sources through use of the `dt-init columns.data` option. This method provides the ability to retrieve that setting after initialisation based on a column selector (see `dt-type column-selector`).

		The value of `dt-init columns.data` that was set during initialisation (including the default of a column index integer) will be returned by this method, including functions (unevaluated). It is important to note that how `dt-init columns.render` is set has no effect on the return value of this method, which is used only for retrieving the value of `dt-init columns.data`.

		It is not possible at this time to use this method as a setter - the data source for a column cannot be changed after initialisation.
