Hi.
I built 3 level header row.
In lowest level only I want to use vertical text painter.
Unfortunately it is applied to second level header as well and I am not able to override it (looks like second header responds to GridRegion.COLUMN_HEADER rather than GridRegion.COLUMN_GROUP_HEADER). Is there way / workaround to set configuration for intermediate levels?

...
ColumnGroupBodyLayerStack bodyLayer = new ColumnGroupBodyLayerStack(bodyDataLayer, columnGroupModel) {};           
ColumnHeaderLayer columnHeaderLayer = new ColumnHeaderLayer(new DefaultColumnHeaderDataLayer(columnHeaderDataProvider), bodyLayer, bodyLayer.getSelectionLayer(), false);        
ColumnGroupHeaderLayer columnGroupHeaderLayer = new ColumnGroupHeaderLayer(columnHeaderLayer, bodyLayer.getSelectionLayer(), columnGroupModel, false);
ColumnGroupGroupHeaderLayer columnGroupGroupHeaderLayer = new ColumnGroupGroupHeaderLayer(columnGroupHeaderLayer, bodyLayer.getSelectionLayer(), columnGroupGroupModel, false);

columnGroupGroupHeaderLayer.addConfiguration(new DefaultColumnHeaderStyleConfiguration() {
    {
        this.cellPainter = new BeveledBorderDecorator(new VerticalTextPainter(false, true, true, true));
    }
            
    @Override
    public void configureRegistry(IConfigRegistry configRegistry) {
        super.configureRegistry(configRegistry);
        configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new BeveledBorderDecorator(new TextPainter()), DisplayMode.NORMAL, GridRegion.COLUMN_GROUP_HEADER);
    }
});

Try to register custom labels and configure the text painters against them

I could not attach labels to second header since LabelAccumulator is called for 2 rows only (0 and -1). When I tried to attach labels to any of these rows I either affected top or bottom header, but not middle one. The second header row is always painted same as bottom.

Hm, well the column grouping stuff is something that definitely needs to be completely refactored.

But I don't understand why the label accumulator is only called for 2 rows. That might be the issue.
