Laravel excel 导出格式不正确

Question

我目前有一个我构建的数组，它像这样转储：

0 => array:11 [▼
  "category_code" => "123"
  "category_name" => "Testing"
  "category_description" => "This is a test category"
  19738 => array:5 [▼
    "identifier" => "720368842943"
    "description" => Test Description One
    "count" => 4
    "details" => array:2 [▼
      0 => array:3 [▼
        "detail_code" => "2751"
        "detail_code2" => "43"
        "detail_specifier" => "Detail One"
      ]
      1 => array:3 [▼
        "detail_code" => "2681"
        "detail_code2" => "9"
        "detail_specifier" => "Detail Two"
      ]
    ]
    "prices" => array:1 [▼
      "01" => "1129.00"
    ]
  ]
  19739 => array:5 [▼
    "identifier" => "720368844121"
    "description" => "Test Description Two"
    "count" => 4
    "details" => array:2 [▼
      0 => array:3 [▼
        "detail_code" => "2751"
        "detail_code2" => "43"
        "detail_specifier" => "Detail One"
      ]
      1 => array:3 [▼
        "detail_code" => "2681"
        "detail_code2" => "9"
        "detail_specifier" => "Detail Two"
      ]
    ]
    "prices" => array:1 [▼
      "01" => "1490.00"
    ]
  ]

我正在使用 laravel excel 以便将其导出为 excel 文件，但它并没有完全按照我的预期工作

当它导出到 excel 时，我只得到顶级信息：

123  |  Testing  |  This is a test category

但我想将该信息作为 header 获取，然后将该类别的每个后续产品作为一行获取，因此对于上面的示例，它看起来像：

123  |  Testing  |  This is a test category
====================================================================================================================
19738  |  720368842943  |  Test Description One  |  4  |  2751  |  43  |  Detail One  |  2681  |  9  |  Detail Two  |  1129.00
19739  |  720368844121  |  Test Description Two  |  4  |  2751  |  43  |  Detail One  |  2681  |  9  |  Detail Two  |  1490.00

这是我正在使用的数组的 excel 代码，上面转储了：

$allCategoryResult= array();

foreach($prices->categories as $category){ 
    $categoryItem = array(); 
    $categoryItem["category_code"] = $category->category_code;
    $categoryItem["category_name"] = $category->category_name; 
    $categoryItem["category_desc"] = $category->category_desc;

    foreach($category->skus as $sku){
        $skuItem = array(); 

        $skuItem["identifier"] = $sku->sku_info->identifier;
        $skuItem["description"] = $sku->sku_info->item->description;
        $skuItem["count"] = $sku->sku_info->item->item_type->count;

        $skuItem["details"] = array(); 
        foreach ($sku->sku_info->details as $details) {
            $detailsItem = array(); 
            $detailsItem["detail_code"] = $details->detail_code;
            $detailsItem["detail_code2"] = $details->detail_code2;
            $detailsItem["detail_specifier"] = $details->detail_specifier;
            $skuItem["details"][] = $detailsItem; 
        }

        $skuItem["prices"] = get_object_vars($sku->prices);


        $itemCode = $sku->sku_info->item->item_code;
        $categoryItem[$itemCode] = $skuItem; 
    }
    $allCategoryResult[] = $categoryItem; 
}


$name = 'Test Export';

    $build = Excel::create($name, function ($excel) use ($allCategoryResult) {

        $excel->setTitle('Test Export');

        $excel->sheet('Test Export', function ($sheet) use ($allCategoryResult) {

            $sheet->fromArray($allCategoryResult);

我猜（这只是一个猜测）header 一代让你失望了。尝试操作您的数据，使每一列都具有相同的索引（注意：代码未经测试，您可能需要更正它）：

$allCategoryResult= array();

foreach($prices->categories as $category){ 
    $categoryItem = array(); 
    $categoryItem["column1"] = $category->category_code;
    $categoryItem["column2"] = $category->category_name; 
    $categoryItem["column3"] = $category->category_desc;

    array_push($allCategoryResult, $categoryItem);    

    foreach($category->skus as $sku){
        $skuItem = array(); 

        $skuItem["column1"] = $sku->sku_info->identifier;
        $skuItem["column2"] = $sku->sku_info->item->description;
        $skuItem["column3"] = $sku->sku_info->item->item_type->count;

        /* We leave that one out for the start
        $skuItem["details"] = array(); 
        foreach ($sku->sku_info->details as $details) {
            $detailsItem = array(); 
            $detailsItem["detail_code"] = $details->detail_code;
            $detailsItem["detail_code2"] = $details->detail_code2;
            $detailsItem["detail_specifier"] = $details->detail_specifier;
            $skuItem["details"][] = $detailsItem; 
        }*/

        $skuItem["column4"] = get_object_vars($sku->prices);

        array_push($allCategoryResult, $skuItem);    
    }
}

这应该会为您提供一个包含如下数据的数组：

Array(
  Array(
    ['column1'] = ...
    ['column2'] = ...
    ... 
  ),
  Array(
    ['column1'] = ...
    ['column2'] = ...
    ... 
  )
)

如果这对您的 excel 有任何改变，请通知我。那将是对图书馆的基本了解，这将有助于我们为您提供帮助。

要回答您的评论，可以在您的 sheet 和 excel object 上调用本机 phpExcel 函数。所以你可以用它来格式化一行粗体：

$sheet->->getStyle('A1:'.$sheet->getHighestColumn().'1')->getFont()->setBold(true);
