Create a Tableview off of an array.

The way I want the program to work is after selecting the "Location" it will grab the data about the location from a text file. That text file will have information on the quantity of different items and the information of each item. When the array is finished grabbing the info and it now knows how many there will be; can I have the TableView be created off of that number?(the quantity of different items)

Hope that makes sense.
