表格下方和旁边的水平和垂直括号

表格下方和旁边的水平和垂直括号

我需要将 Power Point 中制作的一些内容复制到 Latex 投影仪中。一些幻灯片包含各种大小和排列的括号和文本气泡。由于我对整个 Latex 还不熟悉，到目前为止我可能只是把它弄乱了（对此我很抱歉）。我只是真的想知道一种比用 tikz 手动定位这些括号和文本气泡更好的方法来排列它们，因为这是我必须多次执行的操作。此外，我找不到让垂直括号以与示例中类似的方式工作的方法。非常感谢您的帮助。

编辑：我真的很喜欢将 \tikzmark{} 放在某处并将其用作锚点的想法。

期望的结果： 结果

到目前为止，我的方法主要是从一些类似的问题中复制而来的（没有颜色和其他东西以保持其简洁）：

迄今为止

\documentclass[presentation, aspectratio=1610, 12pt, t]{beamer}
\usepackage{tikz} 
\usetikzlibrary{cd,arrows, decorations.markings, backgrounds, shapes.multipart,matrix,positioning, shapes, fit,decorations.pathreplacing,angles,quotes,decorations.pathreplacing,calc}

\usepackage{multirow} %adds the possibility to create columns spanning mulitple rows

\newcommand{\tikzmark}[1]{\tikz[overlay,remember picture] \node (#1) {};}
\newcommand*{\BraceAmplitude}{0.5em}%  Can be tweaked if
\newcommand*{\VerticalOffset}{1.2ex}%  necessary.
\newcommand*{\HorizontalOffset}{0.8ex}%  necessary.
\newcommand*{\InsertUnderBrace}[4][]{%
    \begin{tikzpicture}[overlay,remember picture]
\draw [decoration={brace,amplitude=\BraceAmplitude},decorate, thick,draw=black,text=black,#1]
        ($(#3)+(\HorizontalOffset,-\VerticalOffset)$) -- 
        ($(#2)+(-\HorizontalOffset,-\VerticalOffset)$)

稍微复杂一点，如图tikz：
