public void AddColumn(

	DataType dataType,
	string contentType,

)

Parameters

name

Type: SystemString
The name.

dataType

Type: Spotfire.Dxp.DataDataType
The data type.

contentType

Type: SystemString
The content type.

externalId

Type: SystemString
An identifier for the column. Unlike name this will remain constant throughout the lifetime of column and used to uniquely identify it within the producer.

inputIdentifier

Type: Spotfire.Dxp.Data.VirtualColumnsVirtualColumnInputIdentifier
The identifier for the collection of inputs for this column. This identifier is declared in the public new abstract class VirtualColumnInputIdentifiers that should be present in each VirtualColumnProducer. It is associated with an VirtualColumnInputCollection through usage of the methods CreateInputs, GetInputs and SetInputs on VirtualColumnProducer. The columns of the same producer can have the same or separate inputs and should then be given the corresponding identifiers here. Once a column is associated with an input collection only values from those inputs will be present in the VirtualValueRequests for values in that column.
