我整个下午都在为这个问题而烦恼，希望有人能帮我。本质上，我遇到的问题是，我使用 DTLforeach 循环迭代 .csv 文件中的值并将它们放入表中。我希望在这个表中看到的一件事是一系列形状，它们会根据 .csv 文件中出现的文本改变颜色。
但是到目前为止，每次我尝试这样做时，它似乎只运行一次颜色测试，因此所有形状最终都是相同的颜色，而不是根据文本而不同的颜色。所以我的问题归结为我正在尝试做什么，如果可以的话，你会怎么做？
希望这些都与主题相关，如果这是重复的，我很抱歉，但我搜索过，找不到与我的问题类似的问题。如果这段代码很糟糕，我也很抱歉，我对 LaTeX 相当不熟悉，所以如果有一种非常简单的方法可以做到这一点，我愿意接受建议。
数据在 .csv 文件中看起来像这样，并由编译时添加的命令提供，以便可以从数据库动态生成 .csv 文件：
{"jobRefId","CISKeywords","problemLocation","jobProgress"
"2","Broken, Other","Gate Green NA Ticket Office","Issue Reported"
"4","Blocked, Broken, Flooded","Village Purple Purple 4 Toilet (Disabled)","Issue Reported"
"6","Shower, Blocked, Too Hot","Venue Children/Youth Stepping Stones Shower","Issue Reported"}

答案1
这是一个解决方案：
\documentclass{beamer}
\usepackage{tikz}
\usepackage{xifthen}
\usepackage{longtable}
\usetikzlibrary{shapes}
\usepackage{xcolor}
\usepackage{tabu}
\usepackage{datatool}
\begin{filecontents*}{test.csv}
"jobRefId","CISKeywords","problemLocation","jobProgress"
"2","Broken, Other","Gate Green NA Ticket Office","Issue Reported"
"4","Blocked, Broken, Flooded","Village Purple Purple 4 Toilet (Disabled)","In Progress"
"6","Shower, Blocked, Too Hot","Venue Children/Youth Stepping Stones Shower","Job Complete"
\end{filecontents*}
\DTLloaddb{CIS}{test.csv}
\definecolor{mellowyellow}{RGB}{255,255,199}
\definecolor{darkred}{RGB}{150,0,0}
\definecolor{darkyellow}{RGB}{255,178,0}
\definecolor{darkgreen}{RGB}{0,65,0}
\setbeamercolor{background canvas}{bg=mellowyellow}
\tikzset{
image/.cd,
1/.style = {ellipse, align=center, minimum height = 1.3cm, minimum width = 2.1cm, darkred, fill = darkred},
2/.style = {ellipse, align=center, minimum height = 1.3cm, minimum width = 2.1cm, darkyellow, fill = darkyellow},
3/.style = {ellipse, align=center, minimum height = 1.3cm, minimum width = 2.1cm, darkgreen, fill = darkgreen},
test/.code={
\ifthenelse{\expandafter\isin\expandafter{#1}{Issue Reported}}{\tikzset{image/1}}{

},
}
\newcommand{\jobindicator}[5]{
\node (#1) [xshift=#2cm,yshift=#3cm] [image/test=#4] {\color{mellowyellow}{#5}};
}
\begin{document}
\begin{frame}[allowframebreaks, noframenumbering]
\transduration{5}
\frametitle{\huge{\\[-8pt] Ongoing Jobs Around Site}}
{\tabulinesep=1mm\begin{longtabu}to\linewidth{|X[c,m]|X[c,m]|X[c,m]|}
\firsthline
\bfseries{Where?} & \bfseries{What?} & \bfseries\vspace{4mm} Job Ref \& Status %
\DTLforeach{CIS}{%
\ciskeywords=CISKeywords, \problemlocation=problemLocation, \jobrefid=jobRefId, \jobprogress=jobProgress}
{%
\\ \hline
\problemlocation & \ciskeywords &
\begin{tikzpicture}

\\\lasthline
\end{longtabu}}
\end{frame}
\end{document}
