Your code didn't work, beside it got the problem for non-digit string. Ex:
if i sort this list:
Full slide-out QWERTY
Full QWERTY
Full QWERTY
Numeric with T9 multimedia
Soft QWERTY
Slide-out QWERTY
Full QWERTY
Full QWERTY
Slide-out QWERTY
It still didn't show the correct result.
Note: for this table, I have to add the columns dynamically, so i use
List<String> for column, not just String.
