Custom fields in cart view

[NRE]

Hi, how can I style/format custom fields html in cart view?
I've a lot of custom fields (plugin type) and they're showed as "field name + field value", one per line, without any separator between field name and value.
I need something more "styled" and I need also to hide some of the fields ... any idea?
Thank you.

I think that they are printed by the plugin:

go to the plugin and open the php file which has the same name with the plugin.
The functions are:
plgVmOnViewCart (VM2)
plgVmOnViewCartVM3(VM3)
