Vuetify 数据 table 加载时显示最后一页

Question

如何添加道具“page”，以便 table 在加载时显示最后一页。项目的数量是可变的。我应该做 items.lenght/items-per-page 还是有更好的方法？

<v-data-table
                :headers="headers"
                :items="items"
                :search="search"
                multi-sort
                must-sort
                :sort-by="['date', 'number']"
                class="elevation-1"
                :items-per-page="10"
                :footer-props="{
                    showFirstLastPage:true,
                }"
                :loading="loading"
                height="540"
            ></v-data-table>

@grimdbx 根据你上面的评论是正确的，你已经做了正确的尝试，你只需要用计算结果

设置页面属性

计算的属性总是在页面加载时返回最后一个页码

computed: {
   lastPage() {return Math.ceil(this.items.length/10);}
}

here instead of this.itemsPerPage you can replace with 10, since you have harcoded the items per page as per your above code

最终的工作代码看起来像

<div id="app">
  <v-app id="inspire">
    <v-data-table
      :headers="headers"
      :items="desserts"
      :items-per-page="5"
      class="elevation-1"
      :page="lastPage"
    ></v-data-table>
  </v-app>
</div>

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  computed: {
     lastPage() {return Math.ceil(this.desserts.length/5);}
  },
  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' },
