Table with only some rows

[#1]

Hi all,

I have to make a table (like attached file) in which the dimensions are: sex, age and type.

The expression is the frequency of each type.

How do I show only the first 2 (or 3..) rows for every Type.

For example I need to show only the rows (see table CountType):

Sex     Age     Type      CounType

   F     10         A2          5

   F     10         A1          2

   F     11         A3          4

    F     11         A2          1

    F     12         A3          2

   F     12         A5          2

........................................

...  and so on

How can I do it?

   Thank
