Yes you are right. I missed one group level to simplify the example. Actually I need 4 header rows
using groups. The final design is.
One problem I found is to give unique names to the column group and the other is the number of group
layers. There is the class ColumnGroupGroupHeaderLayer which need a ColumnGroupHeaderLayer as
constructor argument but cant handle ColumnGroupGroupHeaderLayer as argument to construct multi
level groups.
+-----------------------------------------------+
| AAA | BBB |
+-----------------------------------------------+
| AA | BB | AA |
+-----------------------------------------------+
| A | B | C | C | C | C |
+-----------------------------------------------+
| a | b | a | b | a | b | a | b | a | b | a | b |
+-----------------------------------------------+
| | | | | | | | | | | | |

What I did so fare:
IDataProvider dataProvider = new BodyDataProvider();
IDataProvider colHeaderDataProvider = new ColHeaderDataProvider();
IDataProvider rowHeaderDataProvider = new RowHeaderDataProvider();
BodyLayerStack bodyLayer = new BodyLayerStack(dataProvider);
ColumnHeaderLayerStack columnHeaderLayer = new ColumnHeaderLayerStack(colHeaderDataProvider, bodyLayer);
RowHeaderLayerStack rowHeaderLayer = new RowHeaderLayerStack(rowHeaderDataProvider, bodyLayer);
DefaultCornerDataProvider cornerDataProvider = new DefaultCornerDataProvider(colHeaderDataProvider,
rowHeaderDataProvider);
CornerLayer cornerLayer = new CornerLayer(new DataLayer(cornerDataProvider), rowHeaderLayer,
columnGroupHeaderLayerNetwork);
GridLayer gridLayer = new GridLayer(bodyLayer, columnGroupHeaderLayerNetwork, rowHeaderLayer,
cornerLayer);
natTable = new NatTable(parent, gridLayer);
public class ColumnHeaderLayerStack extends AbstractLayerTransform {
public ColumnHeaderLayerStack(IDataProvider dataProvider, BodyLayerStack pBodyLayer) {
DataLayer dataLayer = new DataLayer(dataProvider);
ColumnHeaderLayer colHeaderLayer = new ColumnHeaderLayer(dataLayer, pBodyLayer,
pBodyLayer.getSelectionLayer());
ColumnGroupModel columnGroupModelTrack = new ColumnGroupModel();
columnGroupHeaderLayerTrack = new ColumnGroupHeaderLayer(colHeaderLayer,
pBodyLayer.getSelectionLayer(), columnGroupModelTrack);
columnGroupHeaderLayerTrack.addColumnsIndexesToGroup("", 0, 1);
ColumnGroupModel columnGroupModelLine = new ColumnGroupModel();
ColumnGroupHeaderLayer columnGroupHeaderLayerLine = new
ColumnGroupHeaderLayer(columnGroupHeaderLayerTrack, pBodyLayer.getSelectionLayer(),
columnGroupModelLine);
columnGroupHeaderLayerLine.addColumnsIndexesToGroup("", 0, 1);
ColumnGroupModel columnGroupModelNetwork = new ColumnGroupModel();
columnGroupHeaderLayerNetwork = new ColumnGroupGroupHeaderLayer(columnGroupHeaderLayerLine,
pBodyLayer.getSelectionLayer(), columnGroupModelNetwork);
columnGroupHeaderLayerNetwork.addColumnsIndexesToGroup("", 0, 1);
....
addColumnsIndexesToGroup to all 3 group level
....
setUnderlyingLayer(colHeaderLayer);
}
}

The DisplayConverter works now, see the picture and coresponding code below:
natTable = new NatTable(sashForm_1, gridLayer, false);
natTable.addConfiguration(new DefaultNatTableStyleConfiguration());
natTable.getConfigRegistry().registerConfigAttribute(CellConfigAttributes.DISPLAY_CONVERTER,
new DisplayConverter() {
@Override
public Object canonicalToDisplayValue(Object canonicalValue) {
if (canonicalValue instanceof String) {
String[] lStrings = ((String) canonicalValue).split("/");
if (lStrings.length > 2) {
return lStrings[lStrings.length - 1];
}
}
return canonicalValue;
}
@Override
public Object displayToCanonicalValue(Object displayValue) {
return displayValue;
}
}, DisplayMode.NORMAL, GridRegion.COLUMN_GROUP_HEADER);
natTable.configure();
