有没有办法可以根据投影仪表格的内容自动调整列宽？

Question

正如标题所述，我想创建一个简洁美观的表格，该表格有三列和大约 14 行。如果一个框架无法容纳所有内容，则可以使用两个框架。第一列每行应包含 1 张图片。第二列应仅包含大约 10 到 15 个字符的文本，第三列仅包含数字 - 最多 2 个。这就是为什么我不想让第二列和第三列无缘无故地占用太多空间。这是一个草图：

在 Zarko 的帮助下，我尝试了以下这些，但现在我想把 2 个这样的桌子放在 1 个框架中。我真的很喜欢这些

    \documentclass{beamer}
\usetheme{Berlin}

\setbeamercolor{mycolor}{fg=black,bg=blue!30}

\usepackage{tikz}
\usepackage[export]{adjustbox}

\newsavebox\mytable
\newlength{\mytablelength}
\begin{document}
        \begin{frame} 
    \sbox\mytable{\begin{tabular}{@{}p{0.3\textwidth} |c| c| @{}}
    \hline
      \includegraphics[width=\linewidth,valign=M]{example-image-a}
            & longer text &   some text \\ \hline
              \includegraphics[width=\linewidth,valign=M]{example-image-a}
            & longer text &   some text \\ \hline
                      \includegraphics[width=\linewidth,valign=M]{example-image-a}
            & longer text &   some text \\ \hline
    \end{tabular}
                }
    \settowidth{\mytablelength}{\usebox\mytable}
    \hfil%
    \begin{beamercolorbox}[wd=\mytablelength,sep=1ex,rounded=true,shadow]{mycolor}
        \centering
    \usebox\mytable
        \end{beamercolorbox}
    \end{frame}
   \end{document}

标题不是强制性的。

首先要感谢。我只是想改变第二列的宽度，但它会移动分隔行和列的垂直线和水平线。（把它放在这里只是因为缩进与添加注释方法配合不好）

\begin{tabular}{p{0.45\textwidth}|p{0.25\textwidth}}
    \textcolor{white}{\bf Head 1} & \textcolor{white}{\bf Head 2} \\
    \includegraphics[scale=.1]{Images.png} & \begin{itemize}\item 4\end{itemize}\\ \hline
    \begin{itemize}\item 5\end{itemize} & \begin{itemize}\item 6\end{itemize} \\ \hline
    \begin{itemize}\item \includegraphics[scale=.15]{Im.png}\end{itemize} 
        & \begin{itemize}\item 8\end{itemize} \\ 
\end{tabular}

Answer 1

您的问题不清楚，因此进一步的一切都是基于猜测您所说的“适当的起点”是什么意思......

作为调整表格（添加垂直线、图片大小、颜色等）的起点可以提供以下 MWE：

\documentclass{beamer}
\usetheme{Berlin}

\setbeamercolor{mycolor}{fg=black,bg=blue!30}

\usepackage{tikz}
\usepackage[export]{adjustbox}

\newsavebox\mytable
\newlength{\mytablelength}
\begin{document}

\begin{frame} 
\sbox\mytable{\begin{tabular}{@{}p{0.3\textwidth} c c @{}}
  \includegraphics[width=\linewidth,valign=M]{example-image-a}
        & some longer text &   some text \\
\end{tabular}
            }
\settowidth{\mytablelength}{\usebox\mytable}

\hfil%
\begin{beamercolorbox}[wd=\mytablelength,sep=1ex,rounded=true,shadow]{mycolor}
    \centering
\usebox\mytable
    \end{beamercolorbox}
\end{frame}
\end{document}

这使：

在上面的 MWE 中， 的宽度beamercolorbox被采纳为表格宽度。对于 ，所有复杂功能都添加了保存框，定义新的长度并将宽度设置为用 表格测量。

图像宽度由第一列的宽度决定，即：p{0.3\textwidth}。如果您想更改图片的宽度，只需更改此列的宽度。图片在表格行中垂直居中（因此其他两列中的文本也看起来垂直居中。使用更改valingn选项（随包提供adjustbox）将其更改为 T 或删除它，您可以分别将位置更改为顶部或基线对齐。

为此采用了tcolorbox包。MWE（复杂版本）：

考虑到一张幻灯片上只能放置四行，您可以将线宽定义为 57mm，并将代码简化为 MWE（更简单的版本）：

\RequirePackage[dvipsnames,svgnames,table]{xcolor}
\documentclass{beamer}
\usetheme{Berlin}

\usepackage[utf8]{inputenc}
\usepackage[many]{tcolorbox}

\usepackage[export]{adjustbox}
    \usepackage{array,makecell,tabularx}
\renewcommand\theadfont{\large\bfseries\color{blue!70!black}}

\begin{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}[allowframebreaks]

\tcbset{enhanced,
        width=57mm,
        fonttitle=\sffamily\bfseries, fontupper=\small\sffamily,
        colback=blue!5, colframe=blue!50!black,
        }% end \tcbset
\centering

... further as in MWE above ...

附录（2）： 第一个附录中的建议的改进版本。为了区别开来，我为表格选择了不同的颜色，这样可以轻松更改为所需的颜色。

主要区别：

• 专门为表格定义，tcolorbox表格第一行带有彩色，并添加了模糊阴影（以获得更漂亮的外观）
• 所有列宽均已确定宽度，并测量列中最长单元格（为此，现在定义了两个长度和新的列类型，C用于第二列和第三列的居中）
• 表格中图形的放置（与前面一样，但略有不同）使用adjustbox包。它有助于定义图像的顶部和底部边距以及行中基线的位置（表格的第一部分展示了可能的位置：前两行分别通过选项M和垂直居中m，第三行通过选项顶部对齐t，第三部分底部对齐 /o 选项，默认功能/，其他两部分使用选项M）。

得到的表格第一部分为：
