# Format single node in tikzcd

Is it possible to format a single node in tikzcd? In the below MWE, I would like the \dots cell to not have an ellipse.

MWE

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}

\begin{document}

\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse}}]
0 \arrow[r] & 1 \arrow[r] & \dots \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}

\end{document}


tikzcd is in fact only an improvement of matrix in TikZ.

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}
\begin{document}
\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse}}]
0 \arrow[r] & 1 \arrow[r] & |[draw=none]|\dots \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}
\end{document}


However, to have nice arrows, I think some improvements are needed. Here are some proposals to do so:

1. Use phantom (as suggested by marmot in the comments)

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}
\begin{document}
\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse}}]
0 \arrow[r] & 1 \arrow[r] & |[draw=none]|\dots\vphantom{1} \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}
\end{document}


We can even improve this approach more by using \cdots:

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}
\begin{document}
\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse}}]
0 \arrow[r] & 1 \arrow[r] & |[draw=none]|\cdots\vphantom{1} \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}
\end{document}


2. Use option anchor=center

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}
\begin{document}
\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse,anchor=center}}]
0 \arrow[r] & 1 \arrow[r] & |[draw=none]|\dots \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}
\end{document}


Moreover, to make the height of the nodes consistent, you may need minimum height option (here I apply it to the anchor=center code – you can apply this to any code above):

\documentclass{article}
\usepackage{tikz-cd}
\usetikzlibrary{shapes}
\begin{document}
\begin{figure}
\begin{tikzcd}[cells={nodes={draw=black, ellipse,anchor=center,minimum height=2em}}]
0 \arrow[r] & 1 \arrow[r] & |[draw=none]|\dots \arrow[r] & n-1 \arrow[r] & n
\end{tikzcd}
\end{figure}
\end{document}


• Sorry, I thought I had. – David Poxon Apr 14 '19 at 4:09
• @DavidPoxon No problems :) You're welcome. – user156344 Apr 14 '19 at 4:10
• @marmot Thanks for pointing that out :) I added your proposal and two more to my answer. – user156344 Apr 14 '19 at 4:44
• Out of curiosity, what does \vphantom{1} do here? – David Poxon Apr 14 '19 at 5:19
• @DavidPoxon \phantom{1} gives an invisible 1; \hphantom{1} gives a space which is as wide as a 1, and \vphantom{1} gives a vertical space which is as high as a 1. Read more: tex.stackexchange.com/a/4523/156344 – user156344 Apr 14 '19 at 5:28
