Format single node in tikzcd

Question

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}

Answer 1

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}
