Customizing in-house training table

Hi Been trying to do some modifications to the in-house training content type/display. Neither of which seems to have any effect on the in-house training Content type display, whether we talk about the individual or per node table, or the overview based on courses. There are several things I'd like to do; show date field: instead of merging date in title change duration time field: as some courses span over days instead of just hours show price per lesson, since these occur on separate dates remove or hide score (from anonymous users) In the in-house training main course page it also displays "continue". Clicking this > and you get the info "this course does not have any lessons". Clicking icon top right however display the correct list of in-house training classes. So it would be good to be able to do a bit of training plus be able to modify the table design, even if latter isn't all that important :) Thanks
