To display rows and columns of data in a nice layout like a spreadsheet I use a table like the code here ..

    Table(array) {
         TableColumn("Ticker", value: \\.ticker)
         TableColumn("Other", value: \.other)
     }

To delete a row from the table the advice is to use a ForEach loop. Since I don’t use a ForEach loop, how do I delete rows from the table ? With this code there is no way to attach a .onDelete modifier or a Button

Any advice would be much appreciated

Thank you

Welcome to the forum.

array is the data source.
So if you remove an item in array, the table should update automatically.

Here a very basic example

struct Customer: Identifiable {
    let id = UUID()
    let name: String
    let email: String
}

struct ContentView: View {
    @State var customers =
    [Customer(name: "John Smith",
              email: "john.smith @ example.com"),
     Customer(name: "Jane Doe",
              email: "jane.doe @ example.com"),
     Customer(name: "Bob Johnson",
              email: "bob.johnson @ example.com")]
    
    var body: some View {
        Table(customers) {
            TableColumn("name", value: \.name)
            TableColumn("email", value: \.email)
            
        }
        Button("Remove Jane Doe") {
            customers.removeAll(where: { $0.name == "Jane Doe"} )
        }

    }
}

PS: you have a typo with the double backslash:

\\.ticker
