+2  A: 

I once wrote a series of extension methods to dump a DataTable to CSV quickly... the version on here is only half the solution, but it will allow you to do a one liner dump to CSV. The other half of the solution is just some gold-plating to allow you to choose specific columns, and do custom text formatting. If you are interested I can get that portion to you as well.

I don't know that it provides a better visualization than HTML, but having it in Excel certainly makes for a nice way to sift and sort the data.

+1 - Viewing the table in Excel or Open Office would work pretty well.
