Hiding Pos column

Hi,
I would like to remove the entire “Pos” column from each ranking so that there is no numbering in the list.
I have used the following CSS code and it seems to have worked, but I’d like to have your advice in case you have a better one to suggest.

th.data-rank.sorting {
    display: none;
}

td.data-rank {
    display: none;
}

Thanks in advance.
