# setRowTypes(_:) Creates the row controllers to use when populating the table with data. ``` func setRowTypes(_ rowTypes: [String]) ``` ## Parameters `rowTypes` An array of strings, each of which corresponds to the name of a row controller defined in your storyboard file. The total number of items in this array is the number of rows to be created in the table. ## Discussion Use this method when you want to display more than one type of row in your table. This method removes any existing rows from the table and configures a new set of rows based on the information in the `rowTypes` parameter. For each row, the method also creates an instance of that row’s class and puts the resulting object in an internal array, which you access using the [`rowController(at:)`](/documentation/WatchKit/WKInterfaceTable/rowController(at:)) method. It is your responsibility to configure each new row controller with the data you want to display. The order of the strings in the `rowTypes` parameter determines the order of the row controller objects you retrieve using the [`rowController(at:)`](/documentation/WatchKit/WKInterfaceTable/rowController(at:)) method, with the first row type used to create the row controller at index 0, the second row type used to create the row controller at index 1, and so on. ## See Also [App Programming Guide for watchOS](https://developer.apple.com/library/archive/documentation/General/Conceptual/WatchKitProgrammingGuide/index.html#//apple_ref/doc/uid/TP40014969) --- Copyright © 2026 Apple Inc.
