InsertClause

class InsertClause<T>(val df: DataFrame<T>, val column: DataColumn<*>)

An intermediate class used in the insert operation.

This class itself does not perform any insertions — it is a transitional step before specifying where to insert the new column. It must be followed by one of the inserting methods to produce a new DataFrame with an inserted column.

Use the following methods to perform the insertion:

under - inserts a new column under the specified column group.
after - inserts a new column after the specified column.
at - inserts a new column at the specified position.

See Grammar for more details.
