创建 csv 简单双标题

我正在尝试将前两行作为标题。我希望- - m m m在每一页上都显示单位等，并在下方另设一行。

我不是csvsimple，而且我在手册中也无法找到答案。

第一页如下所示：

第一的

第二：

第二

我已经解决了存在 \delta 等乳胶符号的问题。

另外，我面临的另一个问题是我无法让页眉显示在每一页上。

 \begin{longtable}{lllllllllll}
   \caption{Database of Ropax Ships.}\\
    \toprule
    \csvreader[
        head=false,
        late after line=\\,
        filter equal={\thecsvinputline}{1},
        ]{data_appendix.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
    \midrule
    \endfirsthead
    \toprule
        \csvreader[
        head=false,
        late after line=\\,
        filter equal={\thecsvinputline}{1},
        ]{data_appendix.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
    \midrule
    \endhead
    \midrule
    \endfoot
    \bottomrule
    \endlastfoot
    \csvreader[
        head=false,
        late after line=\\,
        filter not equal={\thecsvinputline}{1},
        ]{data_appendix.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
\end{longtable}

我将非常感激您的帮助。

答案1

嗯，你没有给出 MWE，所以在某些部分我只能猜测，但这里的主要问题是使用 longtable 标题中的前两个 csv 行并省略显示数据的前两个 csv 行。

使用以下代码\endfirsthead：

\csvreader[%
    head=false,
    late after line=\\,
    filter equal={\thecsvinputline}{1},
    ]{\jobname.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
\csvreader[% <====================================================== added
    head=false,
    late after line=\\,
    filter equal={\thecsvinputline}{2}, % <========================= line 2
    ]{\jobname.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
\midrule
\endfirsthead

并且对于\endhead：

\toprule
    \csvreader[
    head=false,
    late after line=\\,
    filter equal={\thecsvinputline}{1},
    ]{\jobname.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
    \csvreader[% <================================================== added 
    head=false,
    late after line=\\,
    filter equal={\thecsvinputline}{2}, % <========================= line 2
    ]{\jobname.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}
\midrule
\endhead

添加的行将把\csvreader带有单位的第二行打印到表头。

要打印完整的表格，我们只需要从第 3 行开始打印（行filter test=\ifnumgreater{\thecsvinputline}{2},检查当前行号是否大于 2）：

\csvreader[%
    head=false,
    late after line=\\,
    filter test=\ifnumgreater{\thecsvinputline}{2},
    ]{\jobname.csv}{}{\csvcoli & \csvcolii & \csvcoliii & \csvcoliv & \csvcolv & \csvcolvi & \csvcolvii & \csvcolviii & \csvcolix}

因此，使用以下完整的 mwe（请注意，标题需要您已经完成的工作，请使用未显示的代码）：
