how to animate matrix element change

Dear there,

I have problem to animate entries of a matrix. The example "tableview" shows how to animate a row of a matrix. I played around try to modify it for my purpose, and had no success. Anyone can help?

Code:

import QtQuick 2.1
import QtQuick.Window 2.1
import QtQuick.Controls 1.1
import QtQuick.XmlListModel 2.0
 
Window {
 
    width: 538
    height: 360
 
    ToolBar{
        id:toolbar
        Row{
            ToolButton{
                text: "hit"
                onClicked:{
                    //I want to randomly select a cell, and flash it like we animate a selected row
                }
            }
        }
    }
 
    ListModel {//each item provides data for a row
        id: largeModel
        Component.onCompleted: {
            for (var i=0 ; i< 4 ; ++i)
                largeModel.append({"col1":0 , "col2": 0, "col3":0, "col4": 0, "col5":0, "col6": 0, "col7":0})
         }
    }
 
    TableView {
