This should work for you, just swap the bbcode_table with tabella in each case, and the same for your custom tr/td etc 🙂

function ntwb_custom_bbcode_table_replace( $text ) {
 
	$text = preg_replace( '/\[bbcode_table\]/i',      htmlspecialchars_decode( '<table>'  ), $text);
	$text = preg_replace( '/\[\/bbcode_table\]/i',    htmlspecialchars_decode( '</table>' ), $text);
	$text = preg_replace( '/\[bbcode_table_tr\]/i',   htmlspecialchars_decode( '<tr>'     ), $text);
	$text = preg_replace( '/\[\/bbcode_table_tr\]/i', htmlspecialchars_decode( '</tr>'    ), $text);
	$text = preg_replace( '/\[bbcode_table_td\]/i',   htmlspecialchars_decode( '<td>'     ), $text);
	$text = preg_replace( '/\[\/bbcode_table_td\]/i', htmlspecialchars_decode( '</td>'    ), $text);
 
	return $text;
	}
