PhpSpreadsheets -如何通过列和行获取单元格坐标？

use PhpOffice\PhpSpreadsheet\IOFactory;

// 加载Excel文件
$spreadsheet = IOFactory::load('path/to/your/excel/file.xlsx');

// 获取第1列第1行的单元格坐标
$column = 1;
$row = 1;
$cellCoordinate = PhpOffice\PhpSpreadsheet\Cell\Coordinate::stringFromColumnIndex($column) . $row;
$cellValue = $spreadsheet->getActiveSheet()->getCell($cellCoordinate)->getValue();

echo "单元格坐标：$cellCoordinate\n";
echo "单元格值：$cellValue\n";
