import QtQuick.Layouts 1.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")


    TableModel
    {
        id:table_model
        TableModelColumn { display: "name" }
        TableModelColumn { display: "item1" }
        TableModelColumn { display: "item2" }
        TableModelColumn { display: "item3" }
        TableModelColumn { display: "item4" }

    }


    Column
    {

        TableView
        {
            id:tabel_view_statistics

            visible: true

            implicitHeight: 100
            implicitWidth: 300

            anchors.horizontalCenter: parent.horizontalCenter


            columnSpacing: -1
            rowSpacing: -1
            clip: true

            delegate: Rectangle
            {
                implicitWidth: 50
                implicitHeight: 25
                border.width: 1

                Text

                    anchors.centerIn: parent
                }
            }
        }

        Label{

            id:label_01
        }

        Button{

            id:button1
            text: "动态数据"

            onClicked: {


                table_model.appendRow(                        {
                                         "name": "树木",
                                         "item1": "6",
                                         "item2": "",
                                         "item3": "",
                                         "item4": ""
                                         })

                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": "",
                                       "item3": "",
                                       "item4": ""
                                       })

                tabel_view_statistics.model = table_model

           


            }
