Атрибут дескриптора vuedraggable не работает

Я пытаюсь использовать vuedraggable внутри таблицы, но не могу изменить порядок строк таблицы с помощью желаемого дескриптора:

App.vue

<template>
  <div id = "app">
    <RowComponent/>

        v-model = "data"

        handle = "[name=dragger]"
        tag = "table"
        @start = "drag = true"
        @end = "drag = false"
    >
        <thead slot = "header">
            <th>
                Placeholder
            </th>
            <th>
                Map Level
            </th>

                Revision
            </th>
