在宏中使用 & 抽象表格的行

在宏中使用 & 抽象表格的行

我正在尝试为表格行创建一个宏。这将允许我以后更改列的顺序，而不必更改每一行的列顺序。

我曾尝试过：

\newcommand\taxrow[9]{%
        \def\paper{#1}%
        \def\method{#2}%
        \def\optobj{#3}%
        \def\workload{#4}%
        \def\sla{#5}%
        \def\perfpred{#6}%
        \def\numofreps{#7}%
        \def\faulttol{#8}%
        \def\failact{#9}%
        \taxrowcond
}

\newcommand\taxrowcond[1]{
        \paper & \method & \optobj & \workload & \sla & \perfpred & \numofreps & \faulttol & \failact & #1
}



\begin{table}[h]
\begin{tabular}{|l|l|l|l|l|l|l|l|l|l|}
\hline
        \taxrow{Paper}{Method}{Optimization Objective}{Workload}{SLA}{Performance Objective}
                {Num. of Reps}{Fault Tolerant}{Failover Action}{Overload Protection}
    &  & & & & & & & & \\ \hline
\end{tabular}
\end{table}

如果我删除“&”符号&，它就会起作用：

\newcommand\taxrow[9]{%
        \def\paper{#1}%
        \def\method{#2}%
        \def\optobj{#3}%
        \def\workload{#4}%
        \def\sla{#5}%
        \def\perfpred{#6}%
        \def\numofreps{#7}%
        \def\faulttol{#8}%
        \def\failact{#9}%
        \taxrowcond
}

\newcommand\taxrowcond[1]{
        \paper
        \method
        \optobj
        \workload
        \sla
        \perfpred
        \numofreps
        \faulttol
        \failact
        #1
}



\begin{table}[h]
\begin{tabular}{|l|l|l|l|l|l|l|l|l|l|}
\hline
        \taxrow{Paper}{Method}{Optimization Objective}{Workload}{SLA}{Performance Objective}
                {Num. of Reps}{Fault Tolerant}{Failover Action}{Overload Protection}
    &  & & & & & & & & \\ \hline
\end{tabular}
\end{table}

答案1

OP 的代码失败有两个原因

  1. 末尾缺少\tabularnewline（或） ，导致字符数超过允许值（由于表格有 10 列，因此最多为 9 个），因此额外的字符将被“添加”到当前行错误\\\tablerowcond&& & & & ...&
  2. \def表格单元格内的元素被分组，因此在该表格单元格之外不可见，在下一个单元格中未定义。如果确实需要，请使用全局定义\gdef。（笔记我根本不推荐这种编码方法...）如果由于某种原因（并非不可能！）\method在外部定义，则将使用外部版本而不是设置为的版本#2！
\documentclass{article}%

更通用的抽象，允许多种表类型。

初始排序顺序是根据 中的顺序得出的\definecolumns，但可以使用 随意更改\sortcolumns，如示例所示。

您可以这样做（但这可能不是最好的解决方案）：

\documentclass{article}
\makeatletter
  \newcommand\taxrow[9]{%
    \gdef\taxpaper{#1}%
    \gdef\method{#2}%
    \gdef\optobj{#3}%
    \gdef\workload{#4}%
    \gdef\sla{#5}%
    \gdef\perfpred{#6}%
    \gdef\numofreps{#7}%
    \gdef\faulttol{#8}%
    \gdef\failact{#9}%
    \taxrowcond
  }
  \def\mytax#1{#1 &}
  \newcommand\taxrowcond[1]{
    \gdef\setthis{\taxpaper \method \optobj \workload \sla \perfpred \numofreps \faulttol \failact}%
        \@for \xx:=\setthis \do{%
                \mytax{\xx}}%
     #1}
\makeatother
\begin{document}

  \begin{table}[h]
    \begin{tabular}{|l|l|l|l|l|l|l|l|l|l|}
      \hline
      \taxrow{Paper}{Method}{Optimization Objective}{Workload}{SLA}{Performance Objective}
      {Num. of Reps}{Fault Tolerant}{Failover Action}{Overload Protection}\\
      &  & & & & & & & & \\ \hline
    \end{tabular}
  \end{table}
\end{document}
