Basically in my tabel I have the first column freezed by default.
I have applied the Freeze command as :

coverSheetNatTable.doCommand(new FreezeColumnCommand(bodyLayer, 0));

I have implemented sort as command on the column header ,it is working fine.

However intially the since the first column is freezed,when I try to apply sort through sort command through column header ,sort does not apply.

If I unfreeze the column(first) ,then apply sort with sort command it works.After that if I again apply freeze ,sort still works.

This means the first time ,sort does not work on freeze column.

AFAIK it works fine in the examples. Maybe you should think about how you execute commands. Since you are trying to do everything programmatically you might break things because of wrong usage.

Maybe calling this command will help

coverSheetNatTable.doCommand(new FreezeColumnCommand(compositeFreezeLayer, 0));

Otherwise try to debug the command execution and see why it is not further processed.

Applying command has not helped.

coverSheetNatTable.doCommand(new FreezeColumnCommand(compositeFreezeLayer, 0));

BodyLayerStack composition is :

columnGroupModel = new ColumnGroupModel();

glazedListsEventLayer = new GlazedListsEventLayer(underlyingLayer,
eventList);
columnReorderLayer = new ColumnGroupReorderLayer(glazedListsEventLayer,columnGroupModel);
columnHideShowLayer = new ColumnHideShowLayer(columnReorderLayer);
columnGroupExpandCollapseLayer = new ColumnGroupExpandCollapseLayer(columnHideShowLayer, columnGroupModel);
// Cat don't need row hide functionality;
rowHideShowLayer = new RowHideShowLayer(glazedListsEventLayer);

selectionLayer = new SelectionLayer(columnGroupExpandCollapseLayer);

viewportLayer = new ViewportLayer(selectionLayer);
freezeLayer = new FreezeLayer(selectionLayer);
compositeFreezeLayer = new CompositeFreezeLayer(freezeLayer,
viewportLayer, selectionLayer);
setUnderlyingLayer(compositeFreezeLayer);

Could setUnderlyingLayer(compositeFreezeLayer); be causing the issue.

Are you calling the FreezeColumnCommand before or after natTable.configure()?

If you are calling it before it won't work because NatTable is in an undefined state.
