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]|dotsvphantom{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]|cdotsvphantom{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}
