数组中存在非法字符

Question

有一个像下面这样的表格，具有自定义宽度，但我无法运行它，有什么想法吗？非常感谢

\documentclass{article}
\usepackage{array}
\begin{document}
\begin{table}[ht]
    \centering
    \begin{tabular}{p{0.015\textwidth}|R{0.37\textwidth}|R{0.12\textwidth}|R{0.08\textwidth}|R{0.02\textwidth}|p{0.35\textwidth}|}
        \hline
        & Sepal.Length & Sepal.Width & Petal.Length & Petal.Width & Species \\ 
        \hline
        1 & 5 & 4 & 1 & 0 & setosa \\ 
        2 & 5 & 3 & 1 & 0 & setosa \\ 
        3 & 5 & 3 & 1 & 0 & setosa \\ 
        4 & 5 & 3 & 2 & 0 & setosa \\ 
        5 & 5 & 4 & 1 & 0 & setosa \\ 
        6 & 5 & 4 & 2 & 0 & setosa \\ 
        \hline
    \end{tabular}
\end{table}
\end{document}

Answer 1

您无需指定列宽。此外，您可以通过对列进行分组来避免表格过分分散。

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[htp]
\centering

\begin{tabular}{
  @{}
  r  % number
  ccccc
  @{}
}
\toprule
& \multicolumn{2}{c}{Sepal} & \multicolumn{2}{c}{Petal} & Species \\
\cmidrule(lr){2-3} \cmidrule(lr){4-5}
& Length & Width & Length & Width & \\ 
\midrule
1 & 5 & 4 & 1 & 0 & setosa \\ 
2 & 5 & 3 & 1 & 0 & setosa \\ 
3 & 5 & 3 & 1 & 0 & setosa \\ 
4 & 5 & 3 & 2 & 0 & setosa \\ 
5 & 5 & 4 & 1 & 0 & setosa \\ 
6 & 5 & 4 & 2 & 0 & setosa \\ 
\bottomrule
\end{tabular}

\end{table}

\end{document}

Answer 2

您尚未定义R列类型。如果您希望它按自己的想法执行操作，我猜您的意思是您可以使用wr（使用相对较新版本的软件包array）但这会将列宽强制为不适合列内容的值，并强制总表格宽度不适合页面。只需使用自然宽度即可使表格更易于阅读，或者最好删除垂直线并使用 booktabs 软件包。

\documentclass{article}
\usepackage{array,booktabs}
\begin{document}
\begin{table}[ht]
    \centering
    \begin{tabular}{wl{0.015\textwidth}|wr{0.37\textwidth}|wr{0.12\textwidth}|wr{0.08\textwidth}|wr{0.02\textwidth}|wr{0.35\textwidth}|}
        \hline
        & Sepal.Length & Sepal.Width & Petal.Length & Petal.Width & Species \\ 
        \hline
        1 & 5 & 4 & 1 & 0 & setosa \\ 
        2 & 5 & 3 & 1 & 0 & setosa \\ 
        3 & 5 & 3 & 1 & 0 & setosa \\ 
        4 & 5 & 3 & 2 & 0 & setosa \\ 
        5 & 5 & 4 & 1 & 0 & setosa \\ 
        6 & 5 & 4 & 2 & 0 & setosa \\ 
        \hline
    \end{tabular}
\end{table}


\begin{table}[ht]
    \centering
    \begin{tabular}{r|r|r|r|r|l|}
        \hline
        & Sepal.Length & Sepal.Width & Petal.Length & Petal.Width & Species \\ 
        \hline
        1 & 5 & 4 & 1 & 0 & setosa \\ 
        2 & 5 & 3 & 1 & 0 & setosa \\ 
        3 & 5 & 3 & 1 & 0 & setosa \\ 
        4 & 5 & 3 & 2 & 0 & setosa \\ 
        5 & 5 & 4 & 1 & 0 & setosa \\ 
        6 & 5 & 4 & 2 & 0 & setosa \\ 
        \hline
    \end{tabular}
\end{table}


\begin{table}[ht]
    \centering
    \begin{tabular}{cccccl}
        \toprule
        & Sepal.Length & Sepal.Width & Petal.Length & Petal.Width & Species \\ 
        \midrule
        1 & 5 & 4 & 1 & 0 & setosa \\ 
        2 & 5 & 3 & 1 & 0 & setosa \\ 
        3 & 5 & 3 & 1 & 0 & setosa \\ 
        4 & 5 & 3 & 2 & 0 & setosa \\ 
        5 & 5 & 4 & 1 & 0 & setosa \\ 
        6 & 5 & 4 & 2 & 0 & setosa \\ 
        \bottomrule
    \end{tabular}
\end{table}
