Perl PDF:：Table中的Colspan

我需要一些帮助，试图在这个PDF表格项目上做一个colspan。在这个示例代码中，我可以解释我正在尝试做什么。我需要用“主要信息”和“次要信息”来做一个“colspan”。我还试图使总计“线”在表上延伸（colspan），以创建一条线来划分此表上的部分。也许我可以传递一个图像来模拟colspan，但是我不知道如何通过数据字符串传递图像代码。我到处找，找不到任何解决办法，也许这里有人以前做过，可以告诉我如何完成他的任务。 这是示例代码，提前感谢您的帮助

在你找到一个合适的解决方案之前，也许一个粗糙的黑客就可以了

改变

到

['Primary Info'、'col$span'、'col$span'、'col$span'、]，

同样地，对于您希望“修复”的其他行。[显然，您可以使用任何其他字符串代替'col$span'，只要它不会自然出现。]

然后为“col$span”制定新规则，使文本与背景颜色相同：

不确定总数是否正是你想要的，但其他的看起来像你想要的，即使有点作弊

} elsif ($cell eq 'col$span') {
    $cell_props->[$j]->[$k] = {
    font => $pdf->corefont("Helvetica", -encoding => "utf8"),
    font_size => 1,
    background_color => '#FFCA00', #
    font_color       => '#FFCA00', #
};
