table按需合计以及合计放在滚动条下面的问题

  // 此处样式 是解决table表格出现横向滚动条时， 合并栏在滚动条下方的问题
  .el-table {
    overflow: auto;
  }
  .el-table__header-wrapper,
  .el-table__body-wrapper,
  .el-table__footer-wrapper {
    overflow: visible;
  }
  .el-table__body-wrapper {
    overflow-x: visible !important;
  }
  /* 这个是为了解决前面样式覆盖之后伪类带出来的竖线 */
  .el-table::after {
    position: relative;
  }
