Execute a FreezeColumnCommand instead of directly access the FreezeLayer.

hI, Thanks your reply. I don't know how to use the FreezeColumnCommand, As I can't found this command example on this website, even in the NatTable example which is download from this website. Please tell me more details how to use it or tell me where this example is.

natTable.doCommand(new FreezeColumnCommand(natTable, 1));

But note that this will only work in case the NatTable is rendered because otherwise the dimensions are not yet initialized.

If you need to set an initial freeze state, you might want to register a listener that unregisters automatically after performing the initial freeze:

PaintListener temp = new PaintListener() {
            @Override
            public void paintControl(PaintEvent e) {
                natTable.doCommand(new FreezeColumnCommand(natTable, 1));
                natTable.removePaintListener(this);
            }
};
natTable.addPaintListener(temp);

Not sure if I showed a different way in the past. Maybe searching the internet helps too.
