你好，我一直在尝试使用 \foreach 循环来填充一个 2 列表格，并且在里面我使用条件来查看是否进行换行：
\newcommand\skillstext[1]{
\renewcommand{\skillstext}{
\begin{tabular}{cc}
\foreach [count=\i] \x in {#1}{
\ifthenelse{\ifodd\value{\i}{true}}{\x \\}{\x &}
}
\end{tabular}
}
}
然而，这也行不通，我也不知道这是否重要，但在错误消息中，它说它对于 \hbox 来说太大了，我认为这是因为它位于我创建的侧边栏中
更新：示例代码 你好，这就是我正在尝试做的工作：

抱歉，忘记说了，这是第二十二个 CV 模板类的修改版本。从这里下载：http://www.latextemplates.com/template/twenty-seconds-resumecv 所有荣誉归于作者
答案1
首先，您\value{\i}将引发错误，因为\i不会扩展为 LaTeX 计数器的名称。其次，不要使用\ifthenelse作为类加载etoolbox。
\ifnumodd \i {\x \\}{\x &}
但它不起作用，因为\foreach不能以这种方式在表格中使用。事实上，跟踪代码显示您正在尝试执行的操作（在我上面的修复之后）：
\skillstext -> \begin {tabular}{cc} \foreach [count=\i ] \x in {{LaTeX},
{SQL},{Suite MS Office},{Leadership},{cohésion d'équipe},{C++}}{\ifnumodd
\i {\x \\}{\x &}} \end {tabular}
这行不通。您需要一个可扩展的循环或一个设计用于表格内部或以\foreach不同方式使用的循环。
啊啊我忘了\foreach使用组。这是本网站的一个众所周知的问题。好的，让我们继续使用如此流行的\foreach：
% Command for printing skills text
\newtoks\skillstexttoks
\newcommand\skillstext[1]{%
\renewcommand{\skillstext}{%
\global\skillstexttoks{\begin{tabular}{cc}}%
\foreach [count=\i] \x in {#1}{%
\ifnumodd\i{\global\skillstexttoks\expandafter\expandafter\expandafter
{\expandafter\the\expandafter\skillstexttoks\x \\}}
{\global\skillstexttoks\expandafter\expandafter\expandafter
{\expandafter\the\expandafter\skillstexttoks\x &}}%
}%
\the\skillstexttoks
\end{tabular}%
}%
}
现在我们得到了
我只能重申我的同事对\skillstext重新定义自身的方式的怀疑。无论如何，这就是我得到的结果。
