使用示例:

 

$excel =new Excel();

	$data=array(

			array('id'=>1,'name'=>'天命1'),

			array('id'=>2,'name'=>'天命2')

		);

	$header=array('ID','角色名');

	$excel->setFileName('aaa');

	$excel->setTitle('工作区1');

	$excel->create($data,$header);

也就是说,从数据库里拿出的二维数组可以直接创建,

 

另外,有的字段为type,保存为int类型的,代表某一个状态的.可以参考create第三个参数

举例:

 

$excel =new Excel();

	$data=array(

			array('id'=>1,'name'=>'天命1','type'=>1),

			array('id'=>2,'name'=>'天命2','type'=>2)

		);

        $replace['type']=array(1=>'猛男',2=>'萌女');

	$header=array('ID','角色名');

	$excel->setFileName('aaa');

	$excel->setTitle('工作区1');

	$excel->create($data,$header,$replace);
