javascript - 输入文本时，具有可扩展行的 Vuetify 数据表会崩溃

Question

当我单击并展开行时，我添加了输入字段，当我尝试将任何值输入到字段中时，行会折叠。

这是我的代码:

new Vue({
  el: '#app',
  data () {
    return {
      headers: [
        {
          text: 'Dessert (100g serving)',
          align: 'left',
          sortable: false,
          value: 'name'
        },
        { text: 'Calories', value: 'calories' },
        { text: 'Fat (g)', value: 'fat' },
        { text: 'Carbs (g)', value: 'carbs' },
        { text: 'Protein (g)', value: 'protein' },
        { text: 'Sodium (mg)', value: 'sodium' },
        { text: 'Calcium (%)', value: 'calcium' },
        { text: 'Iron (%)', value: 'iron' }
      ],
      items: [
        {value: false, name: 'Frozen Yogurt', calories: 159, fat: 6.0, carbs: 24, protein: 4.0, sodium: 87, calcium: '14%', iron: '1%'},
        {value: false, name: 'Ice cream sandwich', calories: 237, fat: 9.0, carbs: 37, protein: 4.3, sodium: 129, calcium: '8%', iron: '1%'}
      ]
    }
  }
})

我的问题的答案，有点乱，问题是由于 item-key，这是我所做的:

// Changing from:
<v-data-table :headers="headers" :items="items" item-key="name">

// Changed to:
<v-data-table :headers="headers" :items="items" item-key="dummyIndexFixForCollapseIssue">

// in `data` using generated random value for 
data () {
  return {
    items: [
      {dummyIndexFixForCollapseIssue: this.generateRandomNumber(), name: 'Frozen Yogurt', calories: 159},
      {dummyIndexFixForCollapseIssue: this.generateRandomNumber(), name: 'Ice cream sandwich', calories: 237}
    ]
  }
}

// here is the `method` to generating random value 
methods: {
  generateRandomNumber () {
    return Number(Math.floor(Math.random() * 90000) + 10000)
  }
}
