Appending an icon to a table column in vuetify data table?

问题

i have a vuetify data table and i am trying to append an icon to just the with protein in it but the way it is being rendered, i am not able to understand how would i go about it?

So i have component which is being imported into the vuetify data table template and that component separately consists of the icon div.

<template>
 <v-data-table>
   <template v-slot:items="props">
      <my-component 
        :protein="props.item.protein"
        :carbs="props.item.carbs" 
        :fats = "props.item.fats"
        :iron="props.item.iron"/>
   </template>
 <v-data-table>
</template>

And in my component i have the template setup like this:-

 <template>
    <tr>
      <td>
        <v-checkbox> </v-checkbox>
      <td>
           <div>        
            <router-link>
         <i class="fa fa-globe"></i>
        </router-link>
    </div>
    </tr>
 </template>

Not sure how i can append the icon to the protein field?

回答1:

If I understood your question correctly, you want dynamic icons for (or appended onto) the protein fields, so here's one way to achieve that:

Vue.component('MyComponent', {
  template: `
    <tr>
      <td><i :class="['fa', 'fa-'.concat(protein)]"></i></td>
      <td>{{carbs}}</td>
      <td>{{fats}}</td>
      <td>{{iron}}</td>
    </tr>
  `,

  props: ['protein', 'carbs', 'fats', 'iron']
});

new Vue({
  el: '#demo',
  
  data: () => ({
    opts: {
      headers: [
        { text: 'Protein', value: 'protein' },
        { text: 'Carbs', value: 'carbs' },
        { text: 'Fats', value: 'fats' },
        { text: 'Iron', value: 'iron' }
      ],
      items: [
        { protein: 'cutlery', carbs: 4, fats: 1, iron: 5 },
        { protein: 'shopping-basket', carbs: 5, fats: 5, iron: 0 },
        { protein: 'beer', carbs: 2, fats: 9, iron: 3 }
      ],
      hideActions: true
    }
  })
})
