我试图将我的模型中的一些数据导出到带有“Laravel excel”的excel scheet,我已经完成了,但我的结果远非我真正需要的
这就是我在下载文件中得到的：
这就是我在下载文件中得到的：
这就是我真正想要实现的目标：
我的控制器部分：
//casting export...
Excel::create('ExcelExport',function($excel) use($filters,$agents) {
$main_arr = array();
foreach($agents as $value){
$main_arr[] = Card::cardForUser($value,$filters)->toArray();
}
$excel->sheet('Sheetshit',function($sheet) use($main_arr) {
//You may ask me "why are you using foreach?"
// and my answer will be:"I don`t KNOW,because it WORKS!"
foreach($main_arr as $one){
$sheet->fromArray($one);
}
});
})->export('xls');
型号部分：
public static function cardForUser($user_id,$filters = array()){
$query = static::UserId($user_id);//just gets 'where user id'
foreach($filters['fields'] as $select){
$query->addSelect($select);
}
return $query->get();
}
public function scopeUserId($query,$user_id) {
return $query->where('user_id','=',$user_id);
}
$filters数组由来自DB的字段名称组成,因此它基本上决定导出中包含哪些列.这意味着我的$main_arr可能有1到5的内部字段长度.每个代理可以在DB中有很多行,或者根本没有行
设置了4个过滤器的$main_arr转储示例：

Sooo …我的问题是：
>如何设置主标题(示例img中的“标题内容”)？
>为什么我的列标题(date_start,ts_category,ts_make,ts_model)会在第一个数组元素中消失？ (你可以在第一个img看到我没有“date start”和第一个子数组的“ts_category”标题.顺便说一下,有时我根本没有第一个子数组的标题！)
>我可以将子数组的标题加粗(ts_make等)吗？怎么样？
>如何为每个代理制作子标题(我计划使用子数组键来显示多个代理)？
更新发布工作代码作为答案.
我不会回答你的所有问题,因为你需要自己查看文档.但是我会告诉你如何获得这样的效果：
而且我认为它不仅仅能解释你做错了什么
Excel::create('ExcelExport',function ($excel) {
$excel->sheet('Sheetname',function ($sheet) {
// first row styling and writing content
$sheet->mergeCells('A1:W1');
$sheet->row(1,function ($row) {
$row->setFontFamily('Comic Sans MS');
$row->setFontSize(30);
});
$sheet->row(1,array('Some big header here'));
// second row styling and writing content
$sheet->row(2,function ($row) {
// call cell manipulation methods
$row->setFontFamily('Comic Sans MS');
$row->setFontSize(15);
$row->setFontWeight('bold');
});
$sheet->row(2,array('Something else here'));
// getting data to display - in my case only one record
$users = User::get()->toArray();
// setting column names for data - you can of course set it manually
$sheet->appendRow(array_keys($users[0])); // column names
// getting last row number (the one we already filled and setting it to bold
$sheet->row($sheet->getHighestRow(),function ($row) {
$row->setFontWeight('bold');
});
// putting users data as next rows
foreach ($users as $user) {
$sheet->appendRow($user);
}
});
})->export('xls');
