使用：

$data = [
	[
		'name' => '小王',
		'age' => 22,
		'gender' => '男'
	],
	[
		'name' => '小美',
		'age' => 23,
		'gender' => '女'
	],
];

exportXlsx($data, [
	'title' => 'excel title',
	'column' => [
		['title' => '姓名', 'field' => 'name', 'width' => 20],
		['title' => '年龄', 'field' => 'age', 'width' => 20],
		['title' => '性别', 'field' => 'gender', 'width' => 20],
