Would it be possible to make this TC be applied to just specified categories, in the same way as Topic Thumbnails and Topic Excerpts?
Workaround
I’ve found that this CSS (when added to the Desktop tab of a theme component) works nicely for my use-case by turning off the functionality for all of the categories except the one I want it to work in:
body:not(.category-ask-the-candidates) {
.topic-list .posters {
display: table-cell;
}
th.author, .custom-author-column {
display: none;
}
}
If you want to use this yourself, simply swap the slug of your specified category(ies) in.
