html中:

    //下拉框  
       <el-form-item label="选择区域">
        <el-select v-model="chick" clearable placeholder="请选择">
          <el-option
            v-for="item in options"
            :key="item.value"
            :label="item.label"
            :value="item.value">
          </el-option>
        </el-select>
      </el-form-item>
      //表格   
     <el-table :data="datalist" >
      <el-table-column label="大区" align="center" prop="area"  />
      <el-table-column label="片区" align="center" prop="pianqu" v-if="display_pq"/>
      <el-table-column label="渠道" align="center" prop="channelName" v-if="display_qd"/>
    </el-table>

data中:

      display_pq:true,
      display_qd:true,         
       options: [{
          value: '选项1',
          label: '片区'
        }, {
          value: '选项2',
          label: '渠道'
        }],
        chick: ''

methods:

    getList() {
      listEffect_sales(this.queryParams).then((response) => {
        this.effect_salesList = response.rows;
        this.total = response.total;
        this.datalist = [];
        this.effect_salesList.forEach((d) => {
        this.datalist.push(d);
        });
      });
    },

watch:

  watch: {
    //选择区域
     chick: function(newVal, oldVal) {
      if(this.chick == '选项1'){
        this.datalist = [];
        this.effect_salesList.forEach((d) => {
        if(d.reportType == "片区"){
          this.datalist.push(d);
          this.display_qd = false;
          this.display_pq = true;
        }
        });    
      }else if(this.chick == '选项2' ){
        this.datalist = [];
        this.effect_salesList.forEach((d) => {
        if(d.reportType == "渠道") {
         this.datalist.push(d);
         this.display_qd = true;
         this.display_pq = false;
        }
         });   
      }else{
        this.datalist = [];
        this.effect_salesList.forEach((d) => {
        this.datalist.push(d);
        this.display_qd = true;
        this.display_pq = true;
        });
      }
