我需要制作一个电路图组件表。组件用 绘制circuitikz。这是我尝试使用的代码。\renewcommand{arraystretch}{2.5}此处注释掉 ，我用它来尝试获得一些垂直填充。代码生成的输出（有和没有 arraystretch 设置）如下所示。
\documentclass[11pt]{article}
\usepackage{circuitikz}
\begin{document}
%\renewcommand{\arraystretch}{2.5}
\begin{tabular}{|c|c|}
\hline
too high &
\begin{circuitikz}
\draw (0,0) to [lamp] (2,0);
\end{circuitikz}
\\ \hline
this one is centred vertically &
\begin{circuitikz}
\draw (0,0) to [european resistor] (2,0);
\end{circuitikz}
\\ \hline
but this on is too high &
\begin{circuitikz}
\draw (0,0) to [empty diode] (2,0);
\end{circuitikz}
\\ \hline
\end{tabular}
\end{document}
我如何创建这样一个表格，其中组件的图表垂直居中，并且在它们各自的表格单元格内有一些垂直填充（最好不需要手动调整每个图表的位置）？
答案1
小修改Phelype Oleinik 的答案。添加的是cellspace用于在单元格内容上方和下方添加垂直空间的包：
\documentclass[11pt]{article}
\usepackage{circuitikz}
\usepackage{array,cellspace}
\setlength\cellspacetoplimit{4pt} % can be placed before "\begin{tabular}"
\setlength\cellspacebottomlimit{4pt}
\begin{document}
\begin{table}[htb]
\tikzset{baseline={([yshift=-0.5ex]current bounding box.center)}}% fixed position of current bounding box
\begin{tabular}{|Sc|Sc|}
\hline
too high
& \begin{circuitikz}
\draw (0,0) to [lamp] (2,0);
\end{circuitikz} \\
\hline
this one is centred vertically
& \begin{circuitikz}
\draw (0,0) to [european resistor] (0,2);
\end{circuitikz} \\
\hline
but this on is too high
& \begin{circuitikz}
\draw (0,0) to [empty diode,anchor=west] (2,0);
\end{circuitikz} \\
\hline
\end{tabular}
\end{table}
\end{document}
答案2
这里的问题是 Ti钾Z 将图片的底部与文本的基线对齐。您可以使用以下命令更改绘图的基线baseline option：
将baseline=(current bounding box.center)文本的基线与图片的中心对齐。为了使它看起来更居中，您可以添加一个yshift将图片中心的宽度与文本的中心对齐。在我看来yshift=-.6ex看起来不错。
您可以将此设置放在\tikzset组中。一旦该组结束，设置将恢复。如果您将此设置放在组中，\begin{table}它将起作用。
\documentclass[11pt]{article}
\usepackage{circuitikz}
\begin{document}
{%
\tikzset{baseline={([yshift=-.6ex]current bounding box.center)}}
\begin{tabular}{|c|c|}
\hline
too high &
\begin{circuitikz}
\draw (0,0) to [lamp] (2,0);
\end{circuitikz}
\\ \hline
this one is centred vertically &
\begin{circuitikz}
\draw (0,0) to [european resistor] (2,0);
\end{circuitikz}
\\ \hline
but this on is too high &
\begin{circuitikz}
\draw (0,0) to [empty diode,anchor=west] (2,0);
\end{circuitikz}
\\ \hline
\end{tabular}%
\renewcommand{\arraystretch}{2.5}
\begin{tabular}{|c|c|}
\hline
too high &
\begin{circuitikz}
\draw (0,0) to [lamp] (2,0);
\end{circuitikz}
\\ \hline
this one is centred vertically &
\begin{circuitikz}
\draw (0,0) to [european resistor] (2,0);
\end{circuitikz}
\\ \hline
but this on is too high &
\begin{circuitikz}
\draw (0,0) to [empty diode,anchor=west] (2,0);
\end{circuitikz}
\\ \hline
\end{tabular}
}
\end{document}
那么，您可能会说：“但是第二个表格中的图片没有居中！”。好吧，文本也没有居中！当您更改时\arraystretch，文本将不会居中，因此，基线不会改变，图片也不会移动。
\arraystretch但是，如果你真的坚持这样做，你可以在和使图片居中的位置之间建立线性关系。我建议反对但是使用这个：
但是互联网上的人们往往不同意某些事情，因此如果您使用此方案，则必须更改\arraystretch，然后使用\calcshift，然后使用\tikzset{baseline={([yshift=\yshift]current bounding box.center)}}。请注意，文本仍位于通常的位置...
\documentclass[11pt]{article}
\usepackage{circuitikz}
\newdimen\yshift

\begin{document}
{%
\calcshift
\tikzset{baseline={([yshift=\yshift]current bounding box.center)}}
\begin{tabular}{|c|c|}

\draw (0,0) to [lamp] (2,0);
