Fields in views organized in 3 collums - fieldgroup?

Hi all,
I am becomming crazy ....
tried half of the night to solve a big problem: tried to organize 12 fields in a views display in 3 collums. No way found.
Ok, what do I want to do?!

I have 12 fields in a custom node-type. the node-title and some cck-fields.
No I want to output them in a unformatted-row-view with fields in the following order:

field1/1....field4........field7
field1/2....field5/1.....field8
field2.......field5/2.....field9
field3.......field6........field10/1
..............................field10/2
..............................field11
..............................field12

Problem: I need a flow display, as all fields can have one OR more lines!!!

I tried using float, absolute, .... but I can't arrange the fields in a smooth way (gaps between vertical fields, ....)
I thought about using the existing fieldgroup to generate "wraps" for the fields - but can't include them in views ;-(

How could I solve this problem?? Generating an individual views-view-***.tpl.php?

Please help!
