如何在 Vuetify 中使用 v-slot 在动态列之间迭代

How can I iterate between dynamic columns with v-slot in Vuetify

我在 data-table 中有动态变化的列。例如 col1、col2、col3 值列。我怎样才能动态地制作 <template v-slot:item.col1="item"> and <template v-slot:item.col2="item">....

您可以在 table 中添加多个模板。因此,您可以为 table.

中的每个列定义一个

这是 vuetify 中沙漠示例的工作示例 API。

<template>
  <v-data-table
    :headers="headers"
    :items="desserts"
    :items-per-page="5"
    class="elevation-1"
  >
    <template v-slot:item.calories=" { item }">
      {{ item.calories.toFixed(2) }}
    </template>

    <template v-slot:item.fat=" { item }">
      {{ item.fat.toFixed(1) }}
    </template>

    <template v-slot:item.carbs=" { item }">
      {{ item.carbs.toFixed(3) }}
    </template>
  </v-data-table>
</template>

<script>
export default {
  name: "Hello",
  data () {
    return {
      headers: [
        {
          text: 'Dessert (100g serving)',
