如何将带有事件的多维数组传递到Codeigner日历库

我正在构建一个日历，遇到了问题。我需要将带有事件的多维数组传递到日历库

这来自Codeingter的用户手册：

$this->load->library('calendar');
$data = array(
               3  => 'http://example.com/news/article/2006/03/',
               7  => 'http://example.com/news/article/2006/07/',
               13 => 'http://example.com/news/article/2006/13/',
               26 => 'http://example.com/news/article/2006/26/'
             );
echo $this->calendar->generate(2006, 6, $data);

有可能传递多维数组吗，比如：

$this->load->library('calendar');
$data = array(
               3  => array('url'=>'article/2006/03/', 'title'=>'Hello1'),
               7  => array('url'=>'article/2006/07/', 'title'=>'Hello2'),
               13 => array('url'=>'article/2006/13/', 'title'=>'Hello3'),
               26 => array('url'=>'article/2006/26/', 'title'=>'Hello4')
             );
echo $this->calendar->generate(2006, 6, $data);

然后以某种方式在日历模板中引用它，类似于：

{cal_cell_content}<h1>{title}</h1><a href="{url}">{day}</a>{/cal_cell_content}

谢谢！
