TableView rowDelegate how to take row index?

Galbarad

import QtQuick 2.2
import QtQuick.Controls 1.2
import QtQuick.Controls 2.0
import QtQuick.Dialogs 1.2

TableView {
        id: tvMain
        
       rowDelegate: Rectangle {
            id: rdRow
            border.width: {
                console.log("rowDelegate", styleData.row, styleData.value,
                            JSON.stringify(styleData) )
                return 0
            }

output is

qml: rowDelegate undefined undefined {"objectName":"","alternate":true,"selected":false,"hasActiveFocus":false,"pressed":false}
qml: rowDelegate undefined undefined {"objectName":"","alternate":false,"selected":false,"hasActiveFocus":false,"pressed":false}

so, my question is:
how I can take row index from rowDelegate? Looks like styleData.row not available(
thanks

hmm, when row selected property "row" - available

qml: rowDelegate {"objectName":"","row":0,"alternate":false,"selected":true,"hasActiveFocus":false,"pressed":true}
qml: rowDelegate {"objectName":"","row":0,"alternate":false,"selected":true,"hasActiveFocus":false,"pressed":false}

but in MouseArea in row delegate styleData.row - available
following code show right click menu for row in place where mouse clicked

rowDelegate: Rectangle {
            id: rdRow
            height: 30

            MouseArea {
                id: maRow
                anchors.fill: parent
                acceptedButtons: Qt.RightButton
                onClicked: {
                    console.log("right click on row", styleData.row, mouseX,
                                mouseY, tvMain.flickableItem.contentY)
                    if ((styleData.row || (styleData.row === 0))
                            && (mouse.button === Qt.RightButton)) {
                        currentRowIdxForMenu = styleData.row
                        cmRow.x = mouseX
                        cmRow.y = mouseY + styleData.row * rdRow.height
                                - tvMain.flickableItem.contentY
                        cmRow.open()
                    }
                }
            }
        }
