How do you add other class's please?

Been on this for a while, anyone know how I get it to find, not only for table-one, but also for other tables with the class names of timetable and table-six please??

		$html = file_get_html($input);
		$tables = $html->find('table[class=table-one]');
		foreach( $tables as $table)


Any help appreciated.


In fact, the question isn’t how to add other class’s, rather, how do you add more class names to that code?
