由于 eqnarray、脚注、表格或标题而出现错误消息？

Question

我知道这不是一个最小示例，但我必须有这么多代码，才能产生我的错误。我已经多次遇到过这个错误，但我无法摆脱它？！我不知道问题出在哪里。对齐和脚注有些不正确，至少这似乎是我的原因？

这是我的代码：

我收到错误：

!$$ 内的 \halign 不正确。\halign

这不是由于特定的对齐环境造成的，例如对齐环境中的拼写错误，我的整个论文中都存在这个问题！

这不是一个答案，但是......我把你的代码压缩为

除了\textheight手动设置之外，这看起来没什么问题。更改任何细节都会让错误消失，所以我猜这里一定有什么可疑之处。我为其他人提供这个作为更好的起点。

Answer 2

这不是一个完整的答案，但它包含所需的 MWE 和一些注释。另外，请注意，由于该错误消息而到达此处的其他人可能会有兴趣查看：修改 \everydisplay 导致 align* 环境停止工作

以下是 MWE 和一些有关它的注释。

\documentclass{scrreprt}
\usepackage{dblfnote}
\begin{document}
  This seems to be a irrelevant\footnote{footnote one}

  \vspace*{20cm}

  \hspace*{14cm} text text\footnote{footnote two}\footnote{footnote three}
\begin{eqnarray}
a & = & b
\end{eqnarray}
\end{document}

上述代码会产生错误。我猜想这与页面末尾附近的换行符、软件包dblfnote和eqnarray环境有关。让我们看看。

将“text text”替换为“xxxxxxxxxxx”，代码将编译时不会出错，即使对于任何其他值也是如此hspace。但是，更改可以连字符的“text text”单词（如“important”）将导致错误。

更改\hspace*{14cm}为\hspace*{13cm}不会产生错误，即使我们将 的值更改vspace为其他任何值（对于较大的值，文本将无法正确显示，但 LaTeX 不会抱怨）。另一方面，保持\hspace*{14cm}（或更大）并将\vspace值减小到\vspace*{20cm}不会产生错误。

这很令人费解...
