【问题描述】：

我有一个生成多个报告的脚本，我一直在使用 DOMPDF 将每个报告转换为 pdf。报告的大小和内容类型各不相同，但通常包含图像、表格和风格化文本。

在我尝试转换的最新报告中，出现以下错误：

我通过验证器运行输入到 DOMPDF 的 html，并且没有错误或警告。该报告确实包含多个表格，但没有一个表格会被强制拆分为多个页面（最长的表格约为一页的三分之一）。除了无效的 HTML 之外，我不确定是什么原因造成的，搜索此错误仅表明这是一个潜在原因。

建议？

我阅读了这篇文章 https://groups.google.com/forum/?fromgroups#!topic/dompdf/yXDoankutY8 并开始挖掘 HTML 错误。

检查您的 CSS 和 HTML 是否都经过验证。我使用 Tidy 函数修复了我的 HTML 并删除了我的 CSS，一点一点地重新实现它。

在我的例子中，这是一个简单的 CSS 规则：

.views-row {
  display: block;
}
