Repeater problem pls help

Hi,

I have two problems with a repeater.
1)

I'd like to have some radio buttons on each row, like this


--------------------------------------------------
Data | Make a choice
-------------------------------------------------
data1 | (o) Option1 ( ) Option2 ( ) Option3
---------------------------------------------------
data2 | ( ) Option1 (o) Option2 ( ) Option3
......


I'd like to have the RBs grouped on rows instead of columns (now I get all Option1 grouped with each other, all Option2 grouped with each other etc).

I use a <input type="radio" ...> for the RBs.

2)
I use alternating row colors. It switches between two colors so that all odd rows are one color, and all even rows are another. I'd like to have for instance three with one color, then three with another color, then three with the first color etc etc. Is that possible???

Best regards and thanks in advance
