使用vant-picker实现自定义内容,根据内容添加图标

 <van-popup v-model="showPicker" position="bottom">
<!--        <van-picker-->
<!--          show-toolbar-->
<!--          :columns="enterpriseList"-->
<!--          @cancel="showPicker = false"-->
<!--          @confirm="onConfirm"-->
<!--        >-->
<!--        <an-picker>-->
 
               <compicker-->
                      :enterpriseList="enterpriseList"
                       @cancel="showPicker = false"
                      @onConfirm="onConfirm">
                </compicker>
 
        <div class="van-picker">
