我正在使用wkhtmltopdf从HTML创建PDF报告，我需要创建一个遵循以下模式的自定义报告：

一些信息在第一页的顶部。
一个可以有1到n行的表格(它应该使用所需的任意页数)
一些信息在最后一页的末尾。

把所有这些放在一起就行了；但是，因为步骤3的信息紧跟在表格之后，所以有没有办法把内容放在页面的末尾？

我甚至不确定这个解决方案是基于CSS还是基于wkhtmltopdf。

请看“页脚和页眉”部分。

您可以结合使用--footer-html和一些JavaScript来完成此任务。

wkhtmltopdf --footer-html footer.html http://www.stackoverflow.com/ so.pdf

我的footer.html的内容基于上面链接中提供的示例：

<!DOCTYPE html>

<script>
window.onload = function() {
    var vars = {};
    var x = document.location.search.substring(1).split('&');
    for (var i in x) {
        var z = x[i].split('=', 2);
        vars[z[0]] = unescape(z[1]);
    }

    //if current page number == last page number
    if (vars['page'] == vars['topage']) {
        document.querySelectorAll('.extra')[0].textContent = 'extra text here';
    }
};
</script>

<style>
.extra {
    color: red;
}
</style>

<div class="extra"></div>

这是一个相当困难的任务，我认为你现在不能用纯CSS解决这个问题(尽管我希望被证明是错的)。

此外，对确定的分页符(page-break-inside: avoid;)的支持也不是最好的。事实上，到目前为止，我认为它不适用于表。您可能会在pagebrake周围拆分一些行。(Webkit呈现一个PDF，然后将其剪切成单页，主要是不管边缘是什么……)

我对这个难题的解决方案是创建单个页面大小的占位符div，然后在生成PDF之前使用一些编程语言在这些占位符之间分发内容。

在这类包装器的最后，您可以在底部添加一个绝对定位的页脚。

下面是一些示例代码：

<!DOCTYPE HTML>
<html lang="en-US">
<head>
    <meta charset="UTF-8">
    <title>Sample Data</title>
    <style>

        * {
            padding: 0;
            margin: 0;
        }   

        .page {
            page-break-inside: avoid;
            height: 1360px;

            position: relative;
        }

        table {
            border-collapse: collapse;
            width: 100%;
        }

        td {
            border: 1px solid #ccc;
            padding: .23em;
        }

        .footer {
            position: absolute;
            color: red;
            bottom: 0;
        }

    </style>
</head>
<body>

<div class="page one">

    <p>
        Some info Here... at the top of first page
    </p>

我不太明白你的意思。“紧跟在表格后面”和“在表格末尾”的内容有什么区别？

tfoot元素可能就是您要查找的内容：

<table>
    <thead>
        <tr><th>Header</th></tr>
    </thead>
    <tfoot>
        <tr><th>Footer</th></tr>
    </tfoot>
    <tbody>
        <tr><td>Data</td></tr>
        <tr><td>Data</td></tr>
        <tr><td>Data</td></tr>
    </tbody>
</table>
