如何用FPDF打印三行表格中不同的列数

require('fpdf.php');

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetTitle('Printing Table with Different Column Numbers');

$columnNumbers = array(3, 4, 5);
$rowHeight = 10; // 行高

$startX = 10; // 表格起始位置的X坐标
$startY = 20; // 表格起始位置的Y坐标
$cellWidth = 30; // 单元格宽度

$currentY = $startY; // 当前Y坐标
foreach ($columnNumbers as $columns) {
    $currentX = $startX; // 当前X坐标
    for ($i = 0; $i < $columns; $i++) {
        $pdf->Rect($currentX, $currentY, $cellWidth, $rowHeight, 'D'); // 创建单元格边框
        $currentX += $cellWidth; // 更新X坐标
    }
    $currentY += $rowHeight; // 更新Y坐标
}

$pdf->Output();
