如何让QML TableView有两列和一个标题？

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    visible: true
    width: 400
    height: 300
    title: "QML TableView Example"

    TableView {
        id: tableView
        anchors.fill: parent

        TableViewColumn {
            role: "column1"
            title: "Column 1"
            width: tableView.width / 2
        }

        TableViewColumn {
            role: "column2"
            title: "Column 2"
            width: tableView.width / 2
        }

        model: ListModel {
            ListElement {
                column1: "Data 1"
                column2: "Data 2"
            }
            ListElement {
                column1: "Data 3"
                column2: "Data 4"
            }
            // Add more ListElements as needed
        }
    }
}
