GWT - datagrid column with integer values

Question

I want to add a column to the datagrid in GWT, the column should show integer values. However, i cannot find any cell that can show an integer. This is my code

    Column<Trade, Integer> sellQuantityColumn = 
            new Column<Trade, Integer>(new NumberCell(NumberFormat.getFormat("##"))) {
                @Override
                public Integer getValue(Trade object) {
                    return object.getSellQty();
                }
            };

This shows an error - The constructor Column(NumberCell) is undefined.

For now, i can show this integer as a string, but is there any way of displaying integer values?

Found the answer myself,

The correct way of using the NumberCell is to use java.lang.Number as the data type and not integer or float.

        Column<Trade, Number> sellQuantityColumn = new Column<Trade, Number>(new NumberCell()) {
            @Override
            public Integer getValue(Trade object) {
                return object.getSellQty();
            }
        };
