How to display multiple columns in tableview using qt quick 2

[James A]

I have created C++ model "chrgHistView" and exposed it to qml. Using the delegate shown below I am able to display only one column role from the model i.e "batteryID" How to display all the columns from the model ?

 TableView {
        id : tableView
        anchors.fill: parent
        columnSpacing: 1
        rowSpacing: 1
        clip: true

        ScrollBar.vertical: ScrollBar{}
        ScrollBar.horizontal: ScrollBar{}
        model: chrgHistView

        delegate: Rectangle {
            implicitWidth: 100
            implicitHeight: 50
            border.width: 1

            Text {
                text: model.batteryID
                anchors.centerIn: parent
            }
        }


    }
