Hi,
I found when I add a column indexes to group the name of the column group name must be unique. In my
case the group name displayed in the table has the same name more then once.
How can I resolve this?
The wanted table layout

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.

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();

Hi,
I will have a look at this after my vacation. For the moment just a hint on configurations. Every layer has its own configuration. Therefore it's more NatTable Style to override the ColumnGroupHeaderLayer configuration (think it is the DefaultColumnGroupHeaderConfiguration) instead of registering directly on the NatTable. But this is just a hint, your way also works.
Greez,
Dirk
