> Suppose we have a requirement like below:
> we want to get the rows with one specified column value larger than A and less than B.
> (They are all decimals or integers)
> namely:                         
>        A < Integer.valueof(column) < B
> Use BinaryComparator will not help us to archive that goal:
> e.g.   suppose A = 100, B = 200, one column value is 110000.
>    So it can satisfy that condition, but it's not the row we wanted.
>     	   
> So I suggest to add one comparator to help implementing this.
