You can use the manage_post-type_custom_column and manage_edit_post-type_columns filters to add your taxonomy column to the post type listing.

add_action( 'admin_init', 'my_admin_init' );
function my_admin_init() {
    add_filter( 'manage_edit-banner_columns', 'my_new_custom_post_column');
    add_action( 'manage_banner_custom_column', 'location_tax_column_info', 10, 2);
}

function my_new_custom_post_column( $column ) {
    $column['location'] = 'Location';

    return $column;
}

function location_tax_column_info( $column_name, $post_id ) {
        $taxonomy = $column_name;
        $post_type = get_post_type($post_id);
        $terms = get_the_terms($post_id, $taxonomy);

        if (!empty($terms) ) {
            foreach ( $terms as $term )
            $post_terms[] =" " .esc_html(sanitize_term_field('name', $term->name, $term->term_id, $taxonomy, 'edit')) . "";
            echo join('', $post_terms );
        }
         else echo 'No Location Set. ';
}
