Question

我需要一些帮助来尝试在我拥有的这个PDF表项目上做一个colspan。在这个示例代码中，我可以解释我想要做什么。我需要使用“主要信息”和“辅助信息”来创建“colspan”。我也试图使总数“线”在表上拉伸（colspan）以创建一条线来划分该表上的部分。也许我可以传递图像来模拟colspan，但无法弄清楚如何通过数据字符串传递图像代码。我到处寻找，我找不到任何解决方案，也许这里有人这样做过，可以告诉我如何完成它。以下是示例代码，并提前感谢您的帮助！

$pdf->mediabox('A4');

在找到合适的解决方案之前，也许会有粗暴的黑客行为。

更改

['Primary Info','','','',],

到

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

并且类似于您想要“修复”的其他行。 [显然，你可以在'col $ span'的地方使用任何其他字符串，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：

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

不确定道达尔是你想要的，但其他人看起来就像你想要的那样，即使它有点作弊。
