columns().names()
Since: DataTables 2.0.0
Get the names for the selected columns.
Description
This method is the plural version of the column().name() method, providing access to multiple column names with a single call. The returned object is a DataTables API instance which is "array-like" (i.e. it behaves like an array in Javascript).
Column names are typically set using the columns.name option and are not seen by the end user at all. They exist only to make access to the data in the table easier for the developer using the software.
