Bootstrap-vue b表,标题中包含过滤器

Question

我有一个用bootstrap-vue生成的表,它显示了系统搜索的结果.

结果表显示给用户的记录,用户可以对它们进行排序并过滤它们.

如何<th>在bootstrap-vue <b-table>元素生成的表头下添加搜索字段？

您可以使用top-row插槽自定义您自己的第一行.请参阅下面的简单例子......

new Vue({
  el: '#app',
  data: {
    filters: {
      id: '',
      issuedBy: '',
      issuedTo: ''
    },
    items: [{id:1234,issuedBy:'Operator',issuedTo:'abcd-efgh'},{id:5678,issuedBy:'User',issuedTo:'ijkl-mnop'}]
  },
  computed: {
    filtered () {
      const filtered = this.items.filter(item => {
        return Object.keys(this.filters).every(key =>
            String(item[key]).includes(this.filters[key]))
      })
      return filtered.length > 0 ? filtered : [{
        id: '',
        issuedBy: '',
        issuedTo: ''
      }]
    }
  }
})

<div id="app">
<b-table striped show-empty :items="filtered">
  <template slot="top-row" slot-scope="{ fields }">
    <td v-for="field in fields" :key="field.key">
      <input v-model="filters[field.key]" :placeholder="field.label">
    </td>
  </template>
</b-table>
</div>

注意:我使用了计算属性来过滤项而不是:filterprop in,b-table因为如果所有项都被过滤掉,包括你的自定义第一行,它就不会呈现行.这样,如果结果为空,我可以提供虚拟数据行.
