Displaying grouped list in a table

Question

This is for question is for MVC and razor view.  I am having trouble with grouping a list, and then building a model that represents that list and displaying the results in a table within a view. For example:
List of items ordered

1. Date
2. CustomerId
3. Location
4. Item
5. Price
6. Quantity

How would I correctly model and display that list in a table if I wanted to group the list by location? And what if I wanted to group the list by two properties, for example, Location and CustomerId?
