我正在处理包含定时数据的表格。数据按时间顺序排序,当日期发生变化时会显示多列,例如:
| day |
| time | event |
| time | event |
| time | event |
| time | event |
| other day |
| time | event |
如果有页面更改,我们会“丢失”日期信息,并且必须返回一页(或几页,包含较长的同一天的系列)才能知道我们正在处理的日期。
因此,我想要一个动态页眉,其中包含通常的静态内容(列名等)和当前日期的指示。
我以为通过在标题中使用宏,并在每天更改时更改宏值,我就能完成工作。不幸的是,标题似乎只被评估一次,并且使用此时的宏值。
有没有关于如何“推迟”此宏评估的想法?或者还有其他方法可以解决我的问题?
这里是对什么(不)起作用的 MWE。
蒂娅,

编辑根据 David Carlisle 的建议,我研究了 supertabular,但没有成功。我似乎忽略了一些明显的东西。以下是 supertabular 版本的(非常简短的)摘录:
\def\mrq{UNDEF}
\tablefirsthead{\hline{}Heure& Durée\\}
\tabletail{\hline}
\tablehead{\hline{}Heure& Durée\\\multicolumn{2}{|c|}{\mrq}\\\hline}
\begin{supertabular}{|ll|}
\hline\multicolumn{2}{|c|}{2020-05-01}\\\hline\def\mrq{2020-05-01}
... table data
\hline\multicolumn{2}{|c|}{2020-05-02}\\\hline\def\mrq{2020-05-02}
\end{supertabular}
我总是在标题中看到“UNDEF”字符串。
