I import a CSV file like this:
Name, Sex, Age, ... , ...
Tom,     M,  12, ... ,...
Bob,      M,  13,
Lily,       F,   11,
Jack,      M,  14,
Micheal, M,   10,
..
It become a list and I call it datalist. Then I want only extract the Name
and Age for each child in the list. I did some thing like:
 ColumPos =
 Map[#[[2]] &,
  Map[Position[datalist, #] &, {"Name",
    "Age"}], {2}]
Map[Extract[#, ColumPos] &, datalist]
Yes, it works. But the code are bit complicated. Any one has any idea to
get it done in a more efficient way?
