element表格的滚动条在合计上边

默认滚动条是在下边的,不好看,这里改一下

　　修改样式.完美解决:

.el-table {
  overflow-x: auto;
}
.el-table__header-wrapper,
.el-table__body-wrapper,
.el-table__footer-wrapper {
  overflow: visible;
}
.el-table::after {
  position: relative;
}
.el-table--scrollable-x .el-table__body-wrapper {
  overflow: visible;
}
