解説

This property applies when TypeDetectionScheme is set to ColumnCount.

The 本製品 uses this value to determine how many columns to generate when a schema definition file is not available, such as when using GenerateSchemaFiles.

This property is useful for controlling schema inference when the number of columns is known in advance but no schema definition exists.
