                tabel_view_statistics.model = table_model


            }
        }

        Button{

            id:button2
            text: "修改数据"

            onClicked: {

                table_model.setRow(0,{
                                       "name": "森林",
                                       "item1": "9",
                                       "item2": "",

            }

        }

        Button{

            id:button3
            text: "数据获取"

            onClicked: {

                label01.text = tabel_view_statistics.model.getRow(0).name
                //console.log( table_model.rows[0].item1)

            }

        }


    }

}
