QML Tableview通过拖动列标题边框来调整列宽

我想通过拖动列标题边框来调整表的列宽，就像在MS Excel中一样。以下代码适用于我生成的表。默认情况下，它不会在TableView（此处列出）中启用。我错过了什么

import QtQuick 2.15
import QtQuick.Controls 2.15
import QtQuick.Layouts 1.3


TableView {
    id: dataPreviewResult

    columnWidthProvider: function (column) { return 100; }
    rowHeightProvider: function (column) { return 30; }
    anchors.fill: parent
    topMargin: columnsHeader1.implicitHeight
    width: parent.width
    ScrollBar.horizontal: ScrollBar{}
    ScrollBar.vertical: ScrollBar{}
    clip: true
    boundsBehavior : Flickable.StopAtBounds


    Connections{
        target: QueryModel

        function onSqlHasData(hasData){
            dataPreviewResult.model = hasData === true? QueryModel: ""
        }

        function onHeaderDataChanged(tableHeaders){
            mainRepeater.model = tableHeaders
        }

    }

    delegate: Rectangle {
        border.color: Constants.darkThemeColor
        border.width: 0.5

        Text {
            text: display
            anchors.fill: parent
            anchors.margins: 10
            verticalAlignment: Text.AlignVCenter
            elide: Text.ElideRight
            color: Constants.lightGrayTextColor
        }
    }
    Rectangle { // mask the headers
        z: 3
        y: dataPreviewResult.contentY
        x: dataPreviewResult.contentX
        width: dataPreviewResult.leftMargin
        height: dataPreviewResult.topMargin
        border.color: Constants.themeColor
        border.width: 0.2
    }

    // Table Header Starts

    Row {
        id: columnsHeader1
        y: dataPreviewResult.contentY
        z: 2
        width: dataPreviewResult.width

        Repeater {
            id: mainRepeater

            Rectangle{
                width: dataPreviewResult.columnWidthProvider(modelData)
                height: 30
                border.color: Constants.darkThemeColor
                color: Constants.lightThemeColor
                border.width: 1

                Text {
                    id: textName
                    text: modelData
                    width: parent.width
                    height: parent.height
                    anchors.centerIn: parent
                    padding: 10
                    font.bold: false
                    verticalAlignment: Text.AlignVCenter
                }
            }
        }
    }

    Layout.fillWidth: true
    Layout.fillHeight: true

}

我已经解决了这个问题，并使用了
