Laravel Excel 样式 CSS 在导出视图时不起作用
Laravel Excel Style with CSS not working while exporting view
我正在尝试使用 laravel Excel 3.1 导出视图。导出工作正常时，我无法设置样式。
我的 laravel 导出看起来像：

好吧，我想将所有单元格的文本居中，并想为 td 和 class strikethroughCell
的文本添加删除线
更新:
看起来我可以使用内联 CSS 更改字体颜色，但我还没有找到解决 line-through css.
的方法
更新 2
完全切换到数组方式

正如我评论的那样，对于更复杂的样式，您需要使用 PhpSpreadsheet 的样式设置方法。有关 phpspreadsheet's docs.
的更多信息
我的方法是使用事件获取底层的 phpspreadsheet 类。
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\RegistersEventListeners;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
class MatrixExcelExport implements FromView, WithEvents
{
use RegistersEventListeners;
public function __construct(...) { ... }
public function view(): View
{
return view('admin.matrix._excel', [...]);
}
public static function afterSheet(AfterSheet $event)
{
// Create Style Arrays
$default_font_style = [
'font' => ['name' => 'Arial', 'size' => 10]
];
$strikethrough = [
'font' => ['strikethrough' => true],
];
// Get Worksheet
$active_sheet = $event->sheet->getDelegate();
// Apply Style Arrays
$active_sheet->getParent()->getDefaultStyle()->applyFromArray($default_font_style);
// strikethrough group of cells (A10 to B12)
$active_sheet->getStyle('A10:B12')->applyFromArray($strikethrough);
// or
$active_sheet->getStyle('A10:B12')->getFont()->setStrikethrough(true);
// single cell
$active_sheet->getStyle('A13')->getFont()->setStrikethrough(true);
}
}
或者您也可以关注laravel excel's styling guide
The WithStyles concerns allows styling columns, cells and rows. This might be useful when you want to make the heading row bold.
namespace App\Exports;
use Maatwebsite\Excel\Concerns\WithStyles;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;
class InvoicesExport implements WithStyles
{
public function styles(Worksheet $sheet)
{
return [
// Style the first row as bold text.
1 => ['font' => ['bold' => true]],
// Styling a specific cell by coordinate.
'B2' => ['font' => ['italic' => true]],
// Styling an entire column.
'C' => ['font' => ['size' => 16]],
];
}
}
For the contents of the styles array, please refer to the PhpSpreadsheet docs(opens new window)
If you prefer the fluent syntax for styling cells, you can do it as follows:
namespace App\Exports;
use Maatwebsite\Excel\Concerns\WithStyles;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;
class InvoicesExport implements WithStyles
{
public function styles(Worksheet $sheet)
{
$sheet->getStyle('B2')->getFont()->setBold(true);
}
}

好吧，我想将所有单元格的文本居中，并想为 td 和 class strikethroughCell
更新:
看起来我可以使用内联 CSS 更改字体颜色，但我还没有找到解决 line-through css.

完全切换到数组方式

正如我评论的那样，对于更复杂的样式，您需要使用 PhpSpreadsheet 的样式设置方法。有关 phpspreadsheet's docs.
的更多信息我的方法是使用事件获取底层的 phpspreadsheet 类。
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\RegistersEventListeners;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
class MatrixExcelExport implements FromView, WithEvents
{
use RegistersEventListeners;
public function __construct(...) { ... }
public function view(): View
{
return view('admin.matrix._excel', [...]);
}
public static function afterSheet(AfterSheet $event)
{
// Create Style Arrays
$default_font_style = [
'font' => ['name' => 'Arial', 'size' => 10]
];
$strikethrough = [
'font' => ['strikethrough' => true],
];
// Get Worksheet
$active_sheet = $event->sheet->getDelegate();
// Apply Style Arrays
$active_sheet->getParent()->getDefaultStyle()->applyFromArray($default_font_style);
// strikethrough group of cells (A10 to B12)
$active_sheet->getStyle('A10:B12')->applyFromArray($strikethrough);
// or
$active_sheet->getStyle('A10:B12')->getFont()->setStrikethrough(true);
// single cell
$active_sheet->getStyle('A13')->getFont()->setStrikethrough(true);
}
}
或者您也可以关注laravel excel's styling guide
The WithStyles concerns allows styling columns, cells and rows. This might be useful when you want to make the heading row bold.
namespace App\Exports; use Maatwebsite\Excel\Concerns\WithStyles; use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet; class InvoicesExport implements WithStyles { public function styles(Worksheet $sheet) { return [ // Style the first row as bold text. 1 => ['font' => ['bold' => true]], // Styling a specific cell by coordinate. 'B2' => ['font' => ['italic' => true]], // Styling an entire column. 'C' => ['font' => ['size' => 16]], ]; } }For the contents of the styles array, please refer to the PhpSpreadsheet docs(opens new window)
If you prefer the fluent syntax for styling cells, you can do it as follows:
namespace App\Exports; use Maatwebsite\Excel\Concerns\WithStyles; use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet; class InvoicesExport implements WithStyles { public function styles(Worksheet $sheet) { $sheet->getStyle('B2')->getFont()->setBold(true); } }
