Element tabel表格border

tabel中添加border样式改最大框 内部写如下代码-----需在scope外写，可在外层添加父级类名防止全局污染

 .el-table--border,
  .el-table--group {
    border-color: rgb(15, 51, 84);
  }
  .el-table--border:after,
  .el-table--group:after,
  .el-table:before {
    background-color: rgb(15, 51, 84);
  }
  .el-table td,
  .el-table--border th,
  .el-table th.is-leaf {
    border-bottom-color: rgb(15, 51, 84);
  }
  .el-table--border td,
  .el-table--border th {
    border-right-color: rgb(15, 51, 84);
  }
