我正在尝试通过突出显示和注释最后一列来注释表格,但是一旦我将\tabnode
和 一起使用,就会出现错位。要么是标记为 的单元格的内容\tabnode
错位在表格之外,要么是单元格的宽度被拉伸(而所有单元格的宽度都应该相等)。修复此问题的正确方法是什么?这是我使用的示例代码:
\documentclass{beamer}
\usepackage[beamer,customcolors]{hf-tikz}
\usepackage{tabularx}
\begin{document}
\begin{frame}{Title}
\newcounter{nodecount}
\newcommand\tabnode[1]{\addtocounter{nodecount}{1}\tikz\node(\arabic{nodecount}){#1};}
\tikzstyle{every picture}+=[remember picture,baseline]
\tikzstyle{every node}+=[inner sep=0pt,anchor=base,
minimum width=1.8cm,align=center,text depth=.25ex,outer sep=1.5pt]
\tikzstyle{every path}+=[thick, rounded corners]
\newcolumntype{g}{>{\columncolor{red}}c}
\begin{table}[ht]
\centering
\begin{tabular}{|c|c|c|g|}\hline
bla & bla & bla & \tabnode{$b_1$}& \hline
bla & bla & bla & bla & \hline
bla & bla & bla & bla & \hline
bla & bla & bla & bla & \hline
bla & bla & bla & bla & \hline
bla & bla & bla & bla & \hline
\end{tabular}
\end{table}
\begin{tikzpicture}[overlay]
\node [right=2cm,above=2cm,minimum width=0pt] at (1) (A) {A};
\draw [<-,out=5,in=180] (1) to (A);
\end{tikzpicture}
\end{frame}
答案1
您的代码有一些错误,会产生错误(特别是,您声明了四列,但使用了五列,并且您忘记了换行命令):下面我纠正了它们并修复了其他方面:
\documentclass{beamer}
\usepackage[beamer,customcolors]{hf-tikz}
\usepackage{tabularx}
\usepackage{colortbl}
\newcounter{nodecount}
\newcolumntype{g}{>{\columncolor{red}}c}
\newcommand\tabnode[1]{%
\addtocounter{nodecount}{1}%
\tikz[remember picture,overlay]\node[inner sep=0pt] (\thenodecount) {#1};}
\begin{document}
\begin{frame}{Title}
\tikzset{
every picture/.style={remember picture,baseline},
every node/.style={
inner sep=0pt,
anchor=base,
minimum width=1.8cm,
align=center,
text depth=.25ex,
outer sep=1.5pt},
every path/.style={
thick,
rounded corners
}
}
\begin{table}
\centering
\begin{tabular}{|c|c|c|g|c|}
\hline
bla & bla & bla & \tabnode{$b_1$} \\ \hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
\end{tabular}
\end{table}
\begin{tikzpicture}[remember picture,overlay]
\node [right=2cm,above=2cm,minimum width=0pt] at (1) (A) {A};
\draw [<-,out=5,in=180] (1) to (A);
\end{tikzpicture}
\end{frame}
\end{document}
不过,我想向您推荐另一种使用该tikzmark
库的方法:总体思路仍然相同;使用 \tikzmark 放置一个“标记”,如 ,\tikzmark{a}
然后您可以使用pic cs
. 来使用该标记,如\draw (pic cs:a) -- ++(1,0);
。完整的示例:
\documentclass{beamer}
\usepackage[beamer,customcolors]{hf-tikz}
\usepackage{tabularx}
\usepackage{colortbl}
\usetikzlibrary{tikzmark}
\newcolumntype{g}{>{\columncolor{red}}c}
\begin{document}
\begin{frame}{Title}
\tikzset{
every picture/.style={remember picture,baseline},
every node/.style={
inner sep=0pt,
anchor=base,
minimum width=1.8cm,
align=center,
text depth=.25ex,
outer sep=1.5pt},
every path/.style={
thick,
rounded corners
}
}
\begin{table}
\centering
\begin{tabular}{|c|c|c|g|c|}
\hline
bla & bla & bla & $b_1$\tikzmark{a} \\ \hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
bla & bla & bla & bla \\\hline
\end{tabular}
\end{table}
\begin{tikzpicture}[remember picture,overlay]
\node [right=2cm,above=2cm,minimum width=0pt] at (pic cs:a) (A) {A};
\draw [<-,out=5,in=180] ([xshift=15pt]{pic cs:a}) to (A);
\end{tikzpicture}
\end{frame}
\end{document}
目前尚不清楚您为什么要加载该hf-tikz
包,因为它在您的 MWE 中没有任何作用。
