tabularx 影响表格编号

Question

我刚刚发现使用tabularx会破坏表格的正常编号（请参见图片）。根据特克斯链接这可能是由于\caption命令超出了tabularx环境范围。但是，当我纠正这个问题时，我在编译时收到错误消息。

有人可以给出建议吗？

Answer 1

这是一种即使在特定上下文中（例如在某个环境中）也没有意义ltablex的特征。tabularxlongtablelongtabletable

对于发布的示例，您可以简单地使用

\usepackage{tabularx}

代替

\usepackage{ltablex}

但是如果您ltablex出于其他原因需要在实际文档中这样做，那么将表计数器放回原位\caption以便tabularx/longtable将其增加到正确值是足够安全的：

   \caption{Cognitive walkthrough goals, tasks and actions}
    \label{table:comparison of techniques}
    \addtocounter{table}{-1}%<<<<<<
    \small
    \begin{tabularx}{\linewidth}{@{}
