我正在尝试在 Laravel 中使用 ajax 方法下载一个 excel 文件。控制器功能：

$myFile = Excel::create($name, function ($excel) use ($export) {
            $excel->sheet('Data', function ($sheet) use ($export) {
                $sheet->fromArray($export);

                $sheet->cells('A1:N1', function ($cells) {

                    $cells->setBackground('#dbdbdb');
                    $cells->setFontColor('#000000');
                    $cells->setFontWeight('bold');
                    $cells->setFont(array(
                        'family' => 'Calibri',
                        'size'   => '9',

                    ));

                });

                $sheet->setStyle(array(
                    'font' => array(
                        'name' => 'Calibri',
                        'size' => 9,

                    ),
                ));

            });
        });
        $myFile   = $myFile->string('xlsx'); 
        $response = array(
            'name' => $name, 
            'file' => "data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64," . base64_encode($myFile), 
        );

        return response()->json($response);

阿贾克斯功能：

$(document).on('click', '.ExportJobs', function() {
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        } …

我有一个简单的查询，使用 maat 网站生成文件

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromCollection;
use App\MyDB;
use Auth;


 class ReportExport implements FromCollection
{
    public function collection()
    {
        $email = Auth::user()->email;
        return MyDB::MyFunction($email)
                ->select('Reference_Number')->get();
    }
}

一切工作正常，但我如何添加标题？

我尝试查看文档，但它让我更加困惑。 https://laravel-excel.maatwebsite.nl/docs/3.0/export/mapping

当我尝试在 Ubuntu 中的服务器上使用 Maatwebsite 3.1 版本导入 Excel 表格时，出现此类错误。

错误：

Maatwebsite \ Excel \ Exceptions \ NoTypeDetectedException

无法检测到 ReaderType 或 WriterType。确保将有效的扩展名传递给文件名或传递显式类型。

控制器

$path = $request->file('mcafile')->getRealPath();
$data = \Excel::import(new UsersImport,$path);

但是相同的导入 excel 代码在我的本地 Windows 机器上运行良好。我上传的每个代码和文件都是相同的。但是在本地和服务器中的工作方式不同。任何人都可以请帮忙。

我正在尝试使用 PHP 7、Laravel 5.8、Maatwebsite Excel 3.1 导出到 excel。我成功地在视图刀片上显示并执行过滤器。

模型：使用 App\UserResponse；

我使用 "maatwebsite/excel": "^3.1" 导出到 Excel，但是当我导出时，值为 0 或 0.0 的列将被忽略，并且单元格留空。示例代码：

public function array(): array
{
    return $this->data;
}

public function columnFormats(): array
{
    return [
        'C' => NumberFormat::FORMAT_TEXT,
        'E' => '0.00',
        'F' => '0.00',
        'G' => '0.00'
    ];
}

public function map($rows): array
{
    return [
        $rows['employeeNumber'],
        $rows['basicSalary'],
        $rows['totalAllowance'],
        $rows['grossSalary']
    ];
}

当列的值为 0 或 0.00 时，单元格中不会插入任何内容。

我使用 Maatwebsite 包在 Laravel 8 中导入 Excel 文件。安装该包并在 app.php 中添加所需的别名和提供程序后，我还执行了以下命令。

php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"

未定义 Maatwebsite\Excel\Concerns\ToModel;
