保持图表/图形样式

Question

当我读写时，是否可以保留 xlsx 文件中的图表样式（形状样式）？我的代码在下面，样式丢失了。

require 'vendor/autoload.php';



use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx AS WXlsx;
use PhpOffice\PhpSpreadsheet\Chart\Chart;
use PhpOffice\PhpSpreadsheet\Settings;
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;


echo "Opening file...<br>";
$spreadsheet = new Xlsx();
$spreadsheet->setIncludeCharts(true);
$spreadsheet = $spreadsheet->load("test.xlsx");

echo "Saving file...<br>";
$fileName = "testKeepChart.xlsx";
$writer = new WXlsx($spreadsheet);
$writer->setIncludeCharts(true);
$writer->setPreCalculateFormulas(false);
$writer->save($fileName);

echo "File saved as $fileName.\n";

Answer 1

当使用类似 excel 的模板（来自现有文件）时，不会加载图表。问题reported here，虽然可能不会修复。
