Cell width calculating issue?

[Handkep]

When the span cell is larger than the cells below it, the last cells under the spanned cell are unequally wide.
what did i wrong?

I'm afraid you need to use X column spec then adjust tabular width manually.

A simplified example

\documentclass{article}
\usepackage{tabularray}

\begin{document}
  \begin{tblr}{
      cell{1}{1}={c=4}{c},
      hlines, vlines
  }
      xxx xxx xxx xxx xxx \\
      0 & 0 & 0 & 0  \\
    \end{tblr}

  \begin{tblr}{
      width=.3\linewidth, % guessed value
      colspec={XXXX},
      cell{1}{1}={c=4}{c},
      hlines, vlines
  }
      xxx xxx xxx xxx xxx \\
      0 & 0 & 0 & 0  \\
    \end{tblr}
\end{document}

Adapt your example:

\documentclass{article}
\usepackage{amsmath, amssymb}
\usepackage{tabularray}

\begin{document}
%\begin{table}[H]
%  \centering
  \SetTblrInner{rowsep=1mm,colsep=2pt}
  \begin{tblr}{
      width=.85\linewidth,
      rows = {valign=m},
      colspec={c *{4}X *{7}c},
      vline{2} = {2-20}{solid, .5mm},
      vline{1,6,9,13} = {2-20}{solid},
      columns = {mode=dmath},
      cell{1}{2,9} = {c=4}{c},
      cell{1}{6} = {c=3}{c},
  }
      & \text{Current state}  &  &  &  & \text{Inputs} &  &  & \text{Next} &  &  &  \\
      % \text{Übergang} & s  &  &  &  & \text{Inputs} &  &  & \text{Next State} &  &  &  \\
      \hline
      \text{Übergang} & x_3 & x_2 & x_1 & x_0 & y_2(0) & y_1(K) & y_0(J) & x_{3+1} & x_{2+1} & x_{1+1} & x_{0+1} \\
      \hline
      0 K \rightarrow 1  & 0 & 0 & 0 & 0 & 0 & 1 & 0 & 0 & 0 & 0 & 1 \\
      1 J \rightarrow 2  & 0 & 0 & 0 & 1 & 0 & 0 & 1 & 0 & 0 & 1 & 0 \\
      2 K \rightarrow 3  & 0 & 0 & 1 & 0 & 0 & 1 & 0 & 0 & 0 & 1 & 1 \\
      3 J \rightarrow 4  & 0 & 0 & 1 & 1 & 0 & 0 & 1 & 0 & 1 & 0 & 0 \\
      4 K \rightarrow 5  & 0 & 1 & 0 & 0 & 0 & 1 & 0 & 0 & 1 & 0 & 1 \\
      5 J \rightarrow 6  & 0 & 1 & 0 & 1 & 0 & 0 & 1 & 0 & 1 & 1 & 0 \\

      8 0 \rightarrow 9  & 1 & 0 & 0 & 0 & 1 & 0 & 0 & 1 & 0 & 0 & 1 \\
      9 0 \rightarrow 10 & 1 & 0 & 0 & 1 & 1 & 0 & 0 & 1 & 0 & 1 & 0 \\

[Handkep]

thank you. that was fast ^^
i dont quite understand how the X columnspec works. Is there any difference to the Q columnspec? there is not much about it in the documentation.
also: whats the c*{4}X ?

[muzimuzhi]

• X stands for equal-width columns, which is firstly (I think) introduced in package tabularx, then adopted by other tabular packages, including tabu and of course tabularray.
• c*{4}X specifies five columns, one centered plus four equal-width. *{<num>}{<spec>} expands to <num> copies of <spec>, so *{4}{X} (braces are optional when there's only one token) is the same as XXXX. You can find doc for *-expression in https://latexref.xyz/tabular.html.
