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

Question

I have dynamically changing columns in data-table. For example an col1, col2, col3-value column. How can I made dynamically the <template v-slot:item.col1="item"> and <template v-slot:item.col2="item">....

Answer 1

You can add multiple templates in your table. So you can just define one for every col in your table.

Here is a working example with the deserts example in the vuetify 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)',
          align: 'start',
          sortable: false,
          value: 'name',
        },
        { text: 'Calories', value: 'calories' },
        { text: 'Fat (g)', value: 'fat' },
        { text: 'Carbs (g)', value: 'carbs' },
        { text: 'Protein (g)', value: 'protein' },
        { text: 'Iron (%)', value: 'iron' },
      ],
