Converting td to th

I have another modification coming from an accessibility audit:

The first cell in each row needs to be converted from a <td> element into a <th> element.

Is there a way to do this with a filter similar to what I used here? https://wordpress.org/support/topic/ada-scopecol-on-first-th/#post-13559434
