PhpOffice\PhpSpreadsheet 无法为列或整个电子表格设置默认格式

Question

我一直在尝试设置特定列或整个电子表格的默认格式。我正在使用 PhpOffice\PhpSpreadsheet 包来创建 Excel 电子表格。有没有办法一次设置整张或整列的格式？

以下是我如何使用该库的代码片段:

require_once 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
// Create new Spreadsheet object
$spreadsheet = new Spreadsheet();
// Set document properties
$spreadsheet->getProperties()->setCreator('Someone')
    ->setLastModifiedBy('Someone Else')
    ->setTitle('XLSX Test Document')
    ->setSubject('Office 2007 XLSX Test Document')
    ->setDescription('PhpOffice')
    ->setKeywords('PhpOffice')
    ->setCategory('PhpOffice');

$header = [
              "Order No",
              "ID",
              "Salutaion",
              "First Name",
              "Last Name",
              "Address"
          ];
$rows = [
            [
                "SDKJFBHIDUF",
                "23123156478978945",
                "Mr.",
                "John",
                "Doe",
                "101, Lorem Ipsum"
            ]
        ];

 $sheet = $spreadsheet->getActiveSheet();
 $sheet->setTitle('Orders');
 $sheet->fromArray($header, null, 'A1');
 $sheet->fromArray($rows, null, 'A2');
 $spreadsheet->setActiveSheetIndex(0);

 header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
 header('Content-Disposition: attachment;filename="samplemultitab-invoice-' . time() . '.xlsx"');
 header('Cache-Control: max-age=0');
 // If you're serving to IE 9, then the following may be needed
 header('Cache-Control: max-age=1');
 // If you're serving to IE over SSL, then the following may be needed
 header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
 header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
 header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
 header('Pragma: public'); // HTTP/1.0
 $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
 $writer->save('php://output');
 exit;

现在我正在修改 /PhpSpreadsheet/Worksheet/Worksheet.php 文件 fromArray 方法如下

$this->getCell($currentColumn . $startRow)->setValue($cellValue);

到

$this->getCell($currentColumn . $startRow)->setValueExplicit($cellValue,\PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);

但我需要一个有效的方法来修复这个通用选项设置。

我遇到了类似的问题，大型 ID 字符串(例如 1234567890123456789)被自动转换为数字并在我的电子表格中显示为 1.23456789012346E+018。

当使用 getStyle($columnIndex)->getNumberFormat()->setFormatCode() 时，您必须使用 PhpOffice\PhpSpreadsheet\Style\NumberFormat 类中的值，尽管存在“FORMAT_TEXT”值，似乎为时已晚，因为单元格值已经被视为数字(Cell\DataType::TYPE_NUMERIC)，而不是纯字符串。

根据我自己的经验，我认为唯一(且繁琐)的解决方案是遍历给定列的单元格以使用 setValueExplicit() 方法。

$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
// Fill the sheet with values using fromArray() method
$spreadsheet->getActiveSheet()->fromArray($dataToFillTheSheet, NULL, 'A1');
// Get the highest row index
$highestRow = $spreadsheet->getActiveSheet()->getHighestRow();
for($i = 1; $i <= $highestRow; $i++) {
  $cell = $spreadsheet->getActiveSheet()->getCellByColumnAndRow($columnIndex, $i);
  $cell->setValueExplicit($cell->getValue(), \PhpOffice\PhpSpreadsheet\Cell\DataType::TYPE_STRING);
}

不过，我很想知道是否有人知道更好的解决方案。
