@ncatanchin I haven't seen such a class. This is a quite efficient approach, because it hides both `<th>` **and** `<td>` elements.

The alternative to do that is like the approach at line 570.
```
@media (max-width: 768px) {
    .table-worklist tr:not(:last-child) > td:nth-child(1),
    .table-worklist tr:not(:last-child) > td:nth-child(2),
    .table-worklist tr:not(:last-child) > td:nth-child(3) {
        max-width: auto;
    }
    .table-worklist tr:not(:last-child) > td:nth-child(1),
    .table-worklist tr:not(:last-child) > td:nth-child(3) {
        min-width: 50px;
    }
    .table-worklist tr:not(:last-child) > td:nth-child(2) {
        min-width: 100px;
    }
    .table-worklist tr:not(:last-child) > th:nth-child(4),
    .table-worklist tr:not(:last-child) > td:nth-child(4) {
        display: none;
    }
    .table-worklist tr:not(:last-child) > th:nth-child(5),
    .table-worklist tr:not(:last-child) > td:nth-child(5) {
        display: none;
    }
    .table-worklist tr:not(:last-child) > th:nth-child(6),
    .table-worklist tr:not(:last-child) > td:nth-child(6) {
        display: none;
    }
}
```

Let me know ;)
