# setNumberOfRows(_:withRowType:) Creates the specified number of row controllers (of the same type) to use in populating the table with data. ``` func setNumberOfRows(_ numberOfRows: Int, withRowType rowType: String) ``` ## Parameters `numberOfRows` The total number of rows to display in the table. `rowType` The name of a row controller defined in your storyboard file. This string corresponds to the value in the Identifier attribute of a row controller definition in your storyboard file. ## Discussion Use this method when you want to populate a table with rows that are all of the same type. This method removes any existing rows from the table and configures a new set of rows based on the information in the `numberOfRows` and `rowType` parameters. 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. --- Copyright © 2026 Apple Inc.
