我正在尝试使用“Laravel excel”将一些数据从我的模型导出到 excel scheet，我已经做到了，但是我的结果与我真正需要的相去甚远

这就是我在下载文件中得到的:

这就是我真正想要完成的:

我的 Controller 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');

模型部分:

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 数组由数据库中的字段名称组成，因此它基本上决定了哪些列包含在导出中。这意味着我的 $main_arr 的内部字段长度可能从 1 到 5。每个代理在 DB 中可以有很多行或根本没有

设置了 4 个过滤器的 $main_arr 转储示例:

 array (size=8)
  0 => 
    array (size=10)

//thats will be first agent
          0 => 
            array (size=4)
              'date_start' => string '06.08.2014 10:00:00' (length=19)

              'ts_model' => string 'Test' (length=4)
        etc...

Sooo...我的问题是:

1. 如何设置主标题(示例 img 中的“Header stuff”)？
2. 为什么我的列标题(date_start、ts_category、ts_make、ts_model)在第一个数组元素中消失了？ (您可以在第一个 img 中看到我没有第一个子数组的“日期开始”和“ts_category”标题。顺便说一句，有时我根本没有第一个子数组的标题!)
3. 我可以将子数组的标题设为粗体(ts_make 等)吗？怎么样？
4. 如何为每个代理制作副标题(我打算使用子数组键显示多个代理)？

最佳答案

我不会回答您所有的问题，因为您需要自己查看文档。但是我会告诉你如何获得这样的效果:

我认为这比解释你做错了什么对你更有帮助

上述excel文件的代码如下:

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');
