// to fix el-table css style
.el-table thead tr{ 
  line-height: 15px;
}

.el-table__fixed-right:has(.el-table__fixed-footer-wrapper), .el-table__fixed:has(.el-table__fixed-footer-wrapper){ 
  bottom: 0 !important;
}

// fix:汇总表格里滚动条区域穿透处理
.el-table__fixed-right, .el-table__fixed{ 
  bottom: 13px !important;
  pointer-events: none;
}
.el-table__fixed-right *, .el-table__fixed *{ 
  pointer-events: auto;
}
.el-table__fixed-right-patch{
  pointer-events: none;
}

// fix:汇总右侧底部添加遮罩
