先上图

思路：使用element ui 自带的栅格，通过控制el-col 的span 属性来设置每行展示多少行（竖着的字段），超过就自动换行；

content1 是表头

content2是返回的数据

getTable()函数是将返回的正常数据进行处理，和表格字段相对应

表格样式在代码中有注释

代码：

      :visible.sync="drawer"
      :direction="direction"
      :before-close="handleClose"

    >
      <div style="margin:31px;">
        <div style="height:408px;overflow-x: auto;overflow-y: hidden;">
