html - Vuetify 动画 v-data-table

Question

<v-data-table         
    :headers="headers"
    :items="rows"
    :items-per-page="30"
     class="elevation-1">

          <template slot="rows" slot-scope="props">
              <td>{{props.rows.username}}</td>
              <td>{{props.rows.password}}</td>
          </template>
          <template v-slot:item.view="{ item }">
              <button v-on:click="viewUser(item.userId)" class="btn btn-outline-info">View Patient Data</button>
          </template>
          <template slot="rows" slot-scope="props">
          <td>{{props.rows.email}}</td>
          </template>
  </v-data-table>

如何做到每次出现新行时它都会淡入而不是“刚出现”？

谢谢

可以在添加新行时向 vuetify 数据表添加动画过渡

<div id="app">
  <v-app id="inspire">
   <v-card>
    <v-btn @click="addRow" color="primary">click to add row</v-btn>
     </v-card>
    <v-data-table
      :headers="headers"
      :items="desserts"
      class="elevation-1"
      hide-default-footer
    >
      <template v-slot:body="props">
        <tbody name="fade" is="transition-group">
          <template >
          <tr class="row" v-for="(item, index) in props.items" :key="index">
            <td>{{item.name}}</td>
            <td>{{item.calories}}</td>
            <td>{{item.fat}}</td>
            <td>{{item.carbs}}</td>
            <td>{{item.protein}}</td>
            <td>{{item.iron}}</td>
           </tr>
            </template>
      </tbody>
      </template>
    </v-data-table>
  </v-app>
</div>

Added this css

.fade-enter-active, .fade-leave-active {
        transition: all 1s;
      }
      .fade-enter, .fade-leave-to /* .fade-leave-active below version 2.1.8 */ {
        opacity: 0;
      }
.row {
  display: table-row;
}

In script

new Vue({

  vuetify: new Vuetify(),
