Thanks for the inputs it helped me.
Further I need to apply certain cell style on the non editable cell.
Is this only achieved through accumulateConfigLabels or any other way.

My NatTable has alomost 25+ columns and based on combinations of diffrent values in certain columns I need to enable or disable column editing for particular row . On disabling the column edit I require to apply diffrent style to those cells.

Currently I following this apporach:
In the GridLayer class ,I have implemented all my condition checks in the getConfigLabels method and based on the checks applies "addLabelOnTop"

bodyDataLayer = new DataLayer(bodyDataProvider) {
@Override
public LabelStack getConfigLabelsByPosition(int columnPosition,
int rowPosition) {

configLabel .addLabelOnTop(CoverSheetNatTable.NONEDITABLE_LABEL);

}
}

Is this apporach o.k. or I needs to Override accmulateConfigLabel() method.
Please recommend what is correct approach and if accumulateConfigLabels() has to be implemented then what is the correct location to overide this class.

No, don't override any methods of layers. You should implement a label overrider/accumulator and register it to the DataLayer

I have added some ComboBox configurations to my NatTabel as follows :

ComboBoxPainter comboBoxPainter = new ComboBoxPainter();
comboBoxCellEditor = new ComboBoxEditor(objType, propName);

if (comboBoxLabelName != null) {

configRegistry.registerConfigAttribute(
EditConfigAttributes.CELL_EDITOR, comboBoxCellEditor,
DisplayMode.EDIT, comboBoxLabelName);
configRegistry.registerConfigAttribute(
CellConfigAttributes.CELL_PAINTER, comboBoxPainter,
DisplayMode.NORMAL, comboBoxLabelName);
}

I also need to add some custom labels to the tabel,and I have implemented it through accmulateConfigLabel:

colLabelAccumulator = new ColumnOverrideLabelAccumulator(bodyDataLayer){

@Override
public void accumulateConfigLabels(LabelStack configLabels,
int columnPosition, int rowPosition) {

CoverSheetRowData rowObject = (CoverSheetRowData) ((GlazedListsDataProvider) gridLayer.getBodyDataProvider)).getRowObject(rowPosition);

if ((columnPropertyAccessor.getColumnIndex(PartViewUICommon.isNoticeReqIdCol) == columnPosition)) configLabels.addLabel(CoverSheetNatTable.EDITABLE_LABEL);}
else {configLabels .addLabel(CoverSheetNatTable.NONEDITABLE_LABEL);
}
}
}

};
All the columns of NatTabel are registered through:
colLabelAccumulator.registerColumnOverrides(colIndx, colNameLabel);
bodyDataLayer.setConfigLabelAccumulator(colLabelAccumulator);

This overwrites the ComboBox editors on my NatTabel.I need to have both the ComboBox and the custom label.

What is the correct way to apply both on the NatTabel.

If you want to apply two labels using different label accumulator, you should use the AggregrateConfigLabelAccumulator which is intended to combine several IConfigLabelAccumulator

No. But you simply need to create an instance of AggregrateConfigLabelAccumulator and add your other IConfigLabelAccumulators to it. Then register the AggregrateConfigLabelAccumulator instance as label accumulator.
