Can my list of items be displayed in multiple rows and columns

I have a list that i need to display on a report, it is just a simple list of names from the database.

It was requested that i have it in a list going across the page, so using a matrix and a column group, however if there are two many names in my list this causes page break issues where the list runs off the right of the page.

I can easily use a row group, and have the list going down the page but we end up with a lot of unused white space to the right of it.

So my question is, is there a way i can get this list to somehow display in a table that might be say three columns wide and then as many rows as needed to display all the names?
