Hi~ alls
recently, i focus on the module "cmd", and find some confused things-- the function named "columnize". Why we need a multiloop as
"for nrows ..
        for col ..
                   for row.."
?? i think we can make a easier method, for example, first, find out the maxlen str in list, and use its length as the standard size to format the list.
Ok, maybe i ignore something, so please give me some hints.
