org.eclipse.nebula.widgets.nattable.layer.DataLayer
Wraps the {@link IDataProvider}, and serves as the data source for all other layers. Also, tracks the size of the columns and the rows using {@link SizeConfig} objects. Since this layer sits directly on top of the datasource, at this layer index == position.
