[Vue warn]: Injection "elForm" not found

1、錯誤描述

2、錯誤原因

     在使用<el-form-item>標簽時，外層沒有加<el-form>，導致出現報錯

   <el-form-item>
        <el-button type="search" @click="searchData">查詢</el-button>
        <el-button type="reset" @click="resetData">重置</el-button>
      </el-form-item>
    </el-form>
    <el-form-item>
      <div>
        <el-table
          v-loading="loading"
          :data="tableData"
          stripe
          border
          highlight-current-row
          style="width: 100%"
          :max-height="tableHeight"
        >

3、解決辦法

      將el-form-item標簽內容移到el-form標簽中
