Sorting inside a table

I have a table which shows details about a customer. I want to split these details into categories. I still want 1 table for the customer, but inside the table I want it to be able to split in details for that customer. For example, if I want to split a table with 6 rows into 3 group, it would look like this:


Customer X
--------------------------
YYYY YYYYY YYYYYYY YYY
YYYY YYYYY YYYYYYY YYY
YYYY YYYYY YYYYYYY YYY
--------------------------
ZZZZ ZZZZZ ZZZZZZZ ZZZ
ZZZZ ZZZZZ ZZZZZZZ ZZZ
--------------------------
AAAA AAAAA AAAAAAA AAA


etc...

I hope its clear.
Thanks
