    <template>
  <div>
    <ul>
      <li v-for="item in li" @click="active = item">{{item}}</li>
    </ul>
    <table>
      <tr v-for="item in items" v-if="item.action == active || active == 'all'">
        <td>{{item.id}}</td>
        <td>{{item.action}}</td>
      </tr>
    </table>
  </div>
</template>

<script>
  export default {
    name: "test",
    data() {
      return {
        active: 'all',
        li: ['all', '', ''],
        items:[
          {
            id:'A2345',
            action:''
          },
          {
            id:'B638',
            action:''
          },
          {
            id:'C863',
            action:''
          }]
      }
    }
  }
</script>

<style lang="stylus" scoped>

</style>
        <table>
      <tr v-for="(item,index) in items" :key="index" v-if="item.action==''">
        <td>{{item.id}}</td>
        <td>{{item.action}}</td>
      </tr>
    </table>

    can be implemented in many ways by referring to the following code. It is suggested that the landlord read more documents, and this problem will be solved naturally. 

    <div class="hello">
  <ul>
    <li @click="select('all')">all</li>
    <li @click="select('unactive')"></li>
    <li @click="select('active')"></li>
    ...
  </ul>
  <table>
    <tr v-for="(item, index) in items" :key="index" v-if="currentType !== item.action">
      <td>{{item.id}}</td>
      <td>{{item.action}}</td>
    </tr>
  </table>
</div>


data() {
  return {
    items:[
      {
        id:'A2345',
        action:''
      },
      {
        id:'B638',
        action:''
      },
      {
        id:'C863',
        action:''
      }],
    currentType: 'all'
  }
},
methods: {
  select(type) {
    if (type === 'all') {
      this.currentType = ''
    } else if (type === 'active') {
      this.currentType = ''
    } ...
  }
}

    use computed to Filter items

    template 

        <ul>
      <li @click="action=''">all</li>
      <li @click="action=''"></li>
      <li @click="action=''"></li>
    </ul>
    <table>
      <tr v-for="item in filterItems">
        <td>{{item.id}}</td>
        <td>{{item.action}}</td>
      </tr>
    </table>

    script 

                data() {
                return {
                    action: ''
                }
            },
            computed() {
                filterItems() {
                    return this.items.filter(item => item.action.includes(this.action)
                    }
                }
            })

    pseudocode makes do.
