组件封装详情

<el-row>
   <el-col :span="24">
   	<!--此处使用 header-cell-style cell-style api修改左侧表头 与 表头样式-->
      <el-table ref="table" :data="tableData" border :cell-style="cellStyle" :header-cell-style="headCellStyle">
      	<!--绑定数据 classroom 为 侧边头-->
          <el-table-column prop="classroom" width="120px" align="center" fixed="left">
              <template slot="header" >
                    <span>培训室</span>

          </el-table-column>
          <!--v-for 循环列 因可能出现多次循环 使用index或id值绑定key的话可能出现重复值 故此处使用id+时间戳-->
          <el-table-column align="center" v-for="(ite,i) in tableHead"  :key="ite.id+Date.now().toString()"> 
          	  <!--此处 以日期为表头 以上下午为二级表头-->
