Latex 如何使乳胶表中的所有单元格都加粗？

根据下表，如何使所有单元格具有粗体样式

MWE：

---

您可以使用

>{…}

在表格参数中设置每列的格式，请参见：

使用

*{num}{str}

语法使其更短、更可读：

\begin{tabular}{*{2}{|>{\bfseries}l} *{4}{|>{\bfseries}c} |}\hline

即“两次向左齐平并加粗”，然后“四次居中并加粗”。（请注意。）

您的MWE：

\documentclass{article}

\usepackage{array} % otherwise you get "Error: Illegal character in array arg."

\begin{document}
    \begin{table}[ht]%
        \centering
        \caption[Data description]{Dataset description}
        \begin{tabular}{*{2}{|>{\bfseries}l} *{4}{|>{\bfseries}c} |}\hline
             &Dataset      &Samples&Numerical&Categorical&Class\\ \hline
            1&Horse        & 300   &  7      & 16        & 2   \\ \hline
            2&Ionosphere   & 351   & 32      &  1        & 2   \\ \hline
            3&Band         & 540   & 13      &  6        & 2   \\ \hline
            4&Australian+MV& 621   &  3      & 11        & 2   \\ \hline
            5&Hepatitis    & 155   &  2      & 17        & 2   \\ \hline
            6&Credit       & 690   &  3      & 12        & 2   \\ \hline
        \end{tabular}
        \label{tab:data}
    \end{table}

\end{document}

您还可以设置整行的格式（本例中不太有趣）-例如，请参阅

注意：您可以使用

\normalfont{}

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{table}[ht]%
% If you want all in bold face then enclose it between {\ bf  }
    \centering {\bf
    \caption[Data description]{Dataset description}
    \begin{tabular}{|l|l|c|c|c|c|}\hline            
       & Dataset      & Samples & Numerical & Categorical & Class\\\hline
