Good design?

[thomus07]

Is the below design OK?

    public abstract class MyAbstract
    {
        public Dictionary<int, ushort> Table
        {
            get;
            protected set;   
        }

        protected MyAbstract()
        {
            PopulateTable();
        }

        protected abstract void PopulateTable();
    }

Table will be initialized inside PopulateTable() by it's derived classes;
