そして、これは私のコントローラーです：
public $helpers = array('PhpExcel');
...
public function excel() {
$this->set('participants', $this->Participant->find('all'));
}
これは私の見解です：
<?php
$this->PhpExcel->createWorksheet();
$this->PhpExcel->setDefaultFont('Calibri', 12);
// define table cells
$table = array(
array('label' => __('id'), 'width' => 'auto', 'filter' => true),
array('label' => __('Förnamn'), 'width' => 'auto', 'filter' => true),
array('label' => __('Efternamn'), 'width' => 'auto', 'filter' => true),
array('label' => __('E-postadress'), 'width' => 'auto', 'filter' => true),
array('label' => __('Mobiltelefon'), 'width' => 'auto', 'filter' => true),

);
// heading
$this->PhpExcel->addTableHeader($table, array('name' => 'Cambria', 'bold' => true));
