Details

It seems that when we introduced saved table configs in NetBox v4.3 (see #14591), dynamic prefetching for table columns was broken in a way that forced prefetching even for hidden columns. his means that tables still rendered correctly, but extraneous database queries are issued in some cases when rendering a table.

The implementation of saved table configs can be adapted to avoid these extraneous queries.
