如何在vuetify表的一个表头中创建下拉选择

<template>
  <v-select v-model="selectedItem" :items="options" label="Select an option"></v-select>
</template>

<script>
  import { VSelect } from 'vuetify/lib';

  export default {
    components: {
      VSelect
    },
    data() {
      return {
        selectedItem: null,
        options: ['Option 1', 'Option 2', 'Option 3'] // 替换为你的选项数组
      };
    }
  };
</script>

<template>
  <v-data-table :headers="headers" :items="data"></v-data-table>
</template>

<script>
  export default {
    data() {
      return {
        headers: [
          { text: 'Name', value: 'name' },
          { text: 'Age', value: 'age' },
          { text: 'Options', value: 'options', sortable: false }
        ],
        data: [
          { name: 'John', age: 25 },
          { name: 'Jane', age: 30 },
          { name: 'Bob', age: 35 }
        ]
      };
    }
  };
</script>

<template>
  <v-data-table :headers="headers" :items="data">
    <template v-slot:[`header.options`]>
      <v-select v-model="selectedItem" :items="options" dense hide-details></v-select>
    </template>
  </v-data-table>
</template>

<script>
  import { VSelect } from 'vuetify/lib';

  export default {
    components: {
      VSelect
    },
    data() {
      return {
        headers: [
          { text: 'Name', value: 'name' },
          { text: 'Age', value: 'age' },
          { text: 'Options', value: 'options', sortable: false }
        ],
        data: [
          { name: 'John', age: 25 },
          { name: 'Jane', age: 30 },
          { name: 'Bob', age: 35 }
        ],
        selectedItem: null,
        options: ['Option 1', 'Option 2', 'Option 3'] // 替换为你的选项数组
      };
    }
  };
</script>
