Laravel Excel模板导出带图片 设置边框线

官网:https://docs.laravel-excel.com

Laravel Excel版本 3.1

1、数据准备

建个2个表,加点数据,控制器中查数据,给模板使用。

表1-order:id, order_no, img_path, note

表2-order_item:id, order_id, sku, num

查数据:

$data = OrderModel::with('item')->get()->toArray();
//使用关联模型hasmany查询
$data = $data[0];
dd($data);

打印结果:

2、模板准备

新建模板:resources/views/order_export.blade.php

<table>
    <thead>
    </thead>
    <tbody>
    <tr>
        <td colspan="2" style="vertical-align: center;"><b>订单号</b></td>
        <td colspan="2" style="vertical-align: center;"><b>备注</b></td>
        <td colspan="2" style="vertical-align: center;"><b>图片</b></td>
    </tr>
    <tr>
        <td colspan="2" style="vertical-align: center;">xxx</td>
        <td colspan="2" style="vertical-align: center;">xxx</td>
        <td colspan="2" style="vertical-align: center;">xxx</td>
    </tr>
    <tr>
        <td colspan="2" style="vertical-align: center;"><b>SKU</b></td>
        <td colspan="2" style="vertical-align: center;"><b>数量</b></td>
    </tr>
    <tr>
        <td colspan="2" style="vertical-align: center;">xxx</td>
        <td colspan="2" style="vertical-align: center;">xxx</td>
    </tr>
    </tbody>
</table>

3、新建导出类

php artisan make:export OrderExport
//app/Exports/OrderExport.php

OrderExport

3.1、实现FromView接口

实现view()方法

use Maatwebsite\Excel\Concerns\FromView;

class OrderExport implements FromView
{
    public function view(): View
    {
        $data = OrderModel::with('item')->get()->toArray();//见上1、数据准备
        return view('order_export', ['data'=>$data[0]]);
    }
}

3.2、调整模板

<table>
    <thead>
    </thead>
    <tbody>
    <tr>
        <td colspan="2" style="vertical-align: center;"><b>订单号</b></td>
        <td colspan="2" style="vertical-align: center;"><b>备注</b></td>
        <td colspan="2" style="vertical-align: center;"><b>图片</b></td>
    </tr>
    <tr>
        <td colspan="2" style="vertical-align: center;">{{ $data['order_no'] }}</td>
        <td colspan="2" style="vertical-align: center;">{{ $data['note'] }}</td>
        <td colspan="2" style="vertical-align: center;">xxx</td>
    </tr>
    <tr>
        <td colspan="2" style="vertical-align: center;"><b>SKU</b></td>
        <td colspan="2" style="vertical-align: center;"><b>数量</b></td>
    </tr>
    @foreach($data['item'] as $k=>$item)
        <tr>
            <td colspan="2" style="vertical-align: center;">{{ $item['sku'] }}</td>
            <td colspan="2" style="vertical-align: center;">{{ $item['num'] }}</td>
        </tr>
    @endforeach
    </tbody>
</table>

3.3、控制器中调用

//控制器中写个方法
public function index()
{
    return Excel::download(new OrderExport(), 'test.xlsx');
}
//路由指向,即可导出

3.4、导出结果

这时候已经完成导出,但有些需要注意的,模板中的css只能内嵌而且只有少数的样式能够使用,具体那些没试,只知道边框线就没效果。还有就是图片img标签也是不适用,导出时出不了效果的。

4、导出带图片

图片导出需要借助 WithEvents 监听事件,这个手册中并没有讲到。

还是上面的导出类:OrderExport,需要实现WithEvents 并实现registerEvents()方法

监听excel表格完成时,插入图片:

use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\WithEvents;

class OrderExport implements FromView,WithEvents
{
    public function view(): View
    {
        $data = OrderModel::with('item')->get()->toArray();
        return view('order_export', ['data'=>$data[0]]);
    }

    public function registerEvents(): array
    {
        return [ AfterSheet::class => function(AfterSheet $event){
            $data = OrderModel::find(1);
            $this->setImage2Excel($event, 'E2' ,$data['img_path'], 0,90);
            //E2时表格横E竖2,图片需要出现的位置
        }];
    }

    /**
     * 添加图片到excel
     * @param $event
     * @param $position:excel表位置
     * @param $path:图片路径
     * @param $width:图片宽度
     * @param $height:图片高度
     * @throws \PhpOffice\PhpSpreadsheet\Exception
     */
    private function setImage2Excel($event, $position, $path, $width,$height){
        $drawing = new\PhpOffice\PhpSpreadsheet\Worksheet\Drawing();
        $drawing->setName('Logo');
        $drawing->setDescription('Logo');
        $drawing->setCoordinates($position);
        $drawing->setPath(public_path($path));
        ($width==0)?null:$drawing->setWidth($width);
        ($height==0)?null:$drawing->setHeight($height);
        $drawing->setWorksheet($event->sheet->getDelegate());
    }
}
  • setImage2Excel()方法是自己封装的,需要多个图片导出时方便调用。

结果

5、设置边框线

<?php
    
namespace App\Exports\Outbound;

use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
use PhpOffice\PhpSpreadsheet\Style\Border;

class InvoiceExport implements FromView, WithEvents
{
    private $data;

    public function __construct(array $data)
    {
        $this->data = $data;
    }

    public function view(): View
    {
        return view('order_export', ['data' => $this->data]);
    }

    public function registerEvents(): array
    {
        return [
            AfterSheet::class => function(AfterSheet $event) {
                $event->sheet->getStyle('A1:E10')->applyFromArray([
                    'borders' => [
                        'allBorders' => [
                            'borderStyle' => Border::BORDER_THIN,
                            'color' => ['argb' => '000000'],
                        ],
                    ],
                ]);
            },
        ];
    }
}
