Shortcodes in crosswords table: Suggestion code

Hi again.
I wrote 2 small functions, which add the shortcode for each crossword in the crosswords table.
If you wish you can add them into the next update.

add_filter('manage_wha_crossword_posts_columns', 'wha_crossword_head');
function wha_crossword_head( $defaults ) {
    foreach($defaults as $key=>$value) {
        if($key=='date') {  // when we find the date column, add the shortcode column before it. 
           $new['shortcode'] = 'Shortcode';
        }    
        $new[$key]=$value;
    }  

    return $new;  
}

add_action( 'manage_wha_crossword_posts_custom_column', 'wha_crossword_content', 10, 2 );

function wha_crossword_content( $column_name, $post_id ) {
    if ($column_name == 'shortcode') {
       echo '<div class="shortcode">[game-crossword id="' . $post_id . '" ]</div>';
    }
}
