C# Best Practice: List<T> of List<T> or List< List<T>> -- better way?

I know you can have a List< List<T> >.  But there is something about it that seems strange to me.

What I am wanting is to have a TableClass which has a List < Row Class >.   Each Row Class is a List< Cell Class >.

Is there a nicer / cleaner way to represent this other than:

TableClass<RowClass<CellClass>>

In other words:

  public class TableClass
    {
        public TableClass() { }

        public List<RowClass> Rows { get; set; }
    }

    public class RowClass
    {
        public RowClass() { }

        public List<CellClass> Cells { get; set; }
    }
    public class CellClass
    {
        public CellClass() { }        
    }

Better way?
