   Suppose you have a custom taxonomy called “genre”, replace {$this->screen->taxonomy} with the name of the custom taxonomy i.e. “genre”

   // Add info to the new columns
   add_action( 'manage_genre_custom_column', 'wpdocs_show_genre_meta_info_in_columns', 10, 3 );
   
   function wpdocs_show_genre_meta_info_in_columns( $string, $columns, $term_id ) {
       switch ( $columns ) {
           // in this example, we had saved some term meta as "genre-characterization"
           case 'characterization' :
               echo esc_html( get_term_meta( $term_id, 'genre-characterization', true ) );
           break;
       }
   }

   The sample below is for adding the column title in the same taxonomy.

   add_filter( 'manage_edit-genre_columns', 'wpdocs_add_new_genre_columns' );
   
   function wpdocs_add_new_genre_columns( $columns ) {
       $columns['characterization'] = __( 'Characterization' );
       return $columns;
   }
