/**
 * Return an array of table values from a particular column, with various
 * filtering options.
 *
 * DataTables 1.10+ provides the `dt-api column().data()` method, built-in to
 * the core, to provide this ability. As such, this method is marked deprecated,
 * but is available for use with legacy version of DataTables. Please use the
 * new API if you are used DataTables 1.10 or newer.
