如何使用PHP XLSX Writer将图像、报表标题和页眉插入到excel工作表中？

use PEAR\Spreadsheet\Excel\Writer;
use PEAR\Spreadsheet\Excel\Writer\BIFFwriter;
use PEAR\Spreadsheet\Excel\Writer\Workbook;
use PEAR\Spreadsheet\Excel\Writer\Worksheet;
use PEAR\Spreadsheet\Excel\Writer\Format;
use PEAR\Spreadsheet\Excel\Writer\Format\Font;

$workbook = new Writer();
$worksheet =& $workbook->addWorksheet('Sheet1');

$imagePath = 'path/to/image.png'; // 图像文件路径
$worksheet->insertBitmap(1, 1, $imagePath, 100, 100); // 在第1行第1列插入图像，大小为100x100像素

$title = '报表标题';
$header = '页眉内容';

// 设置报表标题样式
$titleFormat =& $workbook->addFormat();
$titleFormat->setFontFamily('Arial');
$titleFormat->setBold();

// 设置页眉样式
$headerFormat =& $workbook->addFormat();
$headerFormat->setHeader('Custom Header', $header); // 设置页眉内容

// 在第2行插入报表标题
$worksheet->writeString(1, 0, $title, $titleFormat);

// 设置页眉样式
$worksheet->setHeader('', $headerFormat);

$workbook->send('filename.xlsx'); // 将文件发送到浏览器下载
$workbook->close(); // 关闭文件对象
