我将表格环境表与 TikZ 图表并排放置。但是，这会导致一些奇怪的布局问题并产生额外的空间。这是我使用的代码：
\documentclass[12pt,twoside]{report}
\usepackage[utf8]{inputenc}
\usepackage[margin=0.75in]{geometry}
\usepackage{setspace}
\usepackage{chemfig}
\usepackage{adjustbox}

\usepackage[numbered]{bookmark}
\usepackage[activate={true,nocompatibility},final,tracking=true,kerning=true,spacing=true,factor=1100,stretch=10,shrink=10]{microtype}
\newcommand{\titlehead}[1]{\begin{center}\pdfbookmark[chapter]{#1}{chapter#1}\section*{#1}\end{center}}
\newcommand{\sectionhead}[1]{\pdfbookmark[section]{#1}{sec#1}\section*{#1}\vspace*{-1em}}
\newcommand{\subsechead}[1]{\pdfbookmark[subsection]{#1}{sec#1}\textbf{\underline{#1}}\vspace*{-0.5em}}
\newenvironment{subcalc}[1]{\vspace{0.1cm}\\\underline{#1}\vspace{0.1cm}\\}{\vspace{0.1cm}}

\end{tabular} &

这产生了以下结果（注意分子结构中不必要的间距和奇怪的位置）：
我希望它显示如下内容：
任何能实现这一目标的建议都将非常感激。

不要使用这些\vspace命令。使用包m中的列说明符和tikz 选项。工作示例：arraybaseline=(current bounding box.west)

\microtypecontext{spacing=nonfrench}
