    $spreadsheet = $reader->load('1.xlsx');
    # 获取活动工作薄
    $sheet = $spreadsheet->getActiveSheet();

    # 获取 单元格值 和 坐标
    $cellC1 = $sheet->getCell('B2');
    echo '值: ', $cellC1->getValue(),PHP_EOL;
    echo '坐标: ', $cellC1->getCoordinate(),PHP_EOL;

    $sheet->setCellValue('B2','欧阳锋');

    # 获取 单元格值 和 坐标
    $cellC2 = $sheet->getCell('B2');
    echo '值: ', $cellC2->getValue(),PHP_EOL;
    echo '坐标: ', $cellC2->getCoordinate();
