Question

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，但是我的结果远离我真正需要的内容

这就是我在下载文件中获得的内容： actual laravel excel export

这就是我真正想要实现的目标： export goal

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');

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);

    }

$filters数组由来自DB的字段名称组成，因此它基本上决定了哪些列包含在导出中。这意味着我的$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：

 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)

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。顺便说一句，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？
如何为每个座席制作子标题（我打算使用子阵列键来显示多个座席）？

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： enter image description here

我认为它不仅仅能解释你做错了什么

以上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');

如何设置主标题（示例img中的“标题内容”）？

查看文档，这很容易：

$sheet->prependRow(1, array(
    'Example header'
    ))->cell('A1', function($cell) {
        $cell->setFontWeight('bold');
        $cell->setFontSize(18);
});

我可以将子数组的标题加粗（ts_make等）吗？怎么样？

计算哪些行必须加粗：

$count = 2;
foreach($main_arr as $one){
    $sheet->fromArray($one, null, 'A2');

    $sheet->row($count, function($row) {
        $row->setFontWeight('bold');
    });
    $count += count( $one ) + 1;
}

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）？

以与上述类似的方式：）

在Marcin和r4xz的帮助下，我来到了这个有效的代码：

Excel::create('Filename', function($excel) use($filters, $agents) {

            $excel->sheet('sheetname', function($sheet) use( $agents, $filters) {
                // first row with header title
                $sheet->mergeCells('A1:E1');//merge for title
                $sheet->row(1, function ($row) {
                    $row->setFontSize(18);
                });
                $sheet->row(1, array('Header Stuff') );//add title

                $sub_titles = array(/*content*/);//array for agents names                   

                $count = 2;//pointer for rows with agents name
                foreach($agents as $agent_id){
                    //get agent name.
                    $agent_name = Model::AgentById(Auth::user(), $agent_id);

                    $sheet->appendRow(array($agent_name));//add agent name
                    $sheet->mergeCells('A'.$count.':'.'E'.$count);//merge for agent name
                    $sheet->row($sheet->getHighestRow(), function ($row) {//get last row at the moment and style it
                        //$row->setFontWeight('bold');
                        $row->setFontSize(14);
                    });

                    $cards = CardModel::cardForUser($agent_id, $filters)->toArray();//get cards for agent
                    //if there is cards show them, else show nothing message
                    if(count($cards) > 0){
                        $sheet->appendRow($sub_titles);//add sub-titles of agents fields
                        $sheet->row($sheet->getHighestRow(), function ($row) {
                            $row->setFontWeight('bold');
                        });
                        foreach($cards as $card){//add all agent fields
                            $sheet->appendRow($card);
                        }
                        $count += count($cards) + 2;
                    }
                    else{
                        $sheet->appendRow(array('nothing to show')));//add nothing to show message
                        $sheet->row($sheet->getHighestRow(), function ($row) {
                            $row->setFontWeight('bold');
                        });
                        $count += 2;
                    }
                }
            });

        })->export('xls');

我建议您创建一个包含所需样式的Excel文件，然后将数据附加到此模板文件，请按照以下示例操作：

    public function export_xls($expense_id, $file_format_id){

    $expense      = Expense::find($expense_id);
    $file_format  = FileFormat::find($file_format_id);

    $routes = DB::table('buy_orders')
        ->join('expenses','expenses.id','=','buy_orders.expense_id')
        ->join('users','expenses.user_id','=','users.id')
        ->select(
            'buy_orders.code',
            'buy_orders.cost_center',
            'buy_orders.book_account',
            'buy_orders.active',
            'buy_orders.expenditure',
            'buy_orders.inventory',
            'buy_orders.quantity',
            'buy_orders.price_unit',
            'buy_orders.description',
            'buy_orders.estimated_value',
            'buy_orders.destination',
            'buy_orders.delivery_date'
        )
        ->where('buy_orders.expense_id','=',$expense_id)
        ->orderBy('buy_orders.created_at','desc')
        ->get();

    $data = json_decode(json_encode((array) $routes), true);

    Excel::load('/storage/app/template.xls', function($file) use($expense, $data){

        $file->setActiveSheetIndex(0)->setCellValue('D8', $expense->user->name);
        $file->setActiveSheetIndex(0)->setCellValue('L8', $expense->application_date);
        $file->setActiveSheetIndex(0)->setCellValue('P8', $expense->code);
        $file->setActiveSheetIndex(0)->setCellValue('D45', $expense->description);

        $row = 13;
        foreach($data as $key => $temp) {
            $col = 1;
            foreach(array_keys($temp) as $value) {
                $file->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $temp[$value]);
                $col++;
            }
            $row++;
        }
    })->export('xls');
}

这个想法是make和array然后使用setCellValueByColumnAndRow方法附加
