after the elementUI sums up the column, if there are many items in the column, a scroll bar will appear, and the scroll bar will be above the total row. Our test has given me a bug, for details, please see the following figure

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

* Special note: override the global style, do not write it in scoped, and the outer layer cannot wrap the parent class (if there is a better way to leave a message, my method is wild)
