由于表格比页面宽，最右边会出现一条黑色条纹。我尝试\\在第一行的单词之间添加，但这似乎不是正确的答案，因为它会破坏所有内容。
我的问题是，在不改变字体大小的情况下，如何才能使第一行（\toprule和之间\midrule）变窄？
\documentclass{article}
\usepackage{amssymb}
\usepackage{booktabs,threeparttable}
\begin{document}
\begin{table}[ht]
\caption{Synthesizable circuits summary.}
\label{tab:summary}
\centering
\begin{threeparttable}
\begin{tabular}{lccccc}
\toprule
$\;$ & TDC~[4] & LDO~[8] & VCO~[10] & Flash~ADC~[9] & VCO-based~ADC~[18] \\
\midrule
\textbf{Technology~(nm)} & 65 & 130 & 65 & 90 & 65 \\
\textbf{Synthesizable} & Yes & Yes & Yes & Yes & Yes\textsuperscript{\textdaggerdbl} \\
\textbf{Supply Voltage~(V)} & 1.2* & 0.6 & 1.2 & 1.2\textsuperscript{$\blacklozenge$} & 1.2* \\
\textbf{Power~(mW)} & 0.010-0.150\textsuperscript{\textbullet} & --- & --- & 34.8\textsuperscript{$\blacklozenge$} & 1.4 \\
\textbf{Dye Area~(mm\textsuperscript{2})} & 0.001 & --- & --- & 0.18 & --- \\
\bottomrule
\end{tabular}
\begin{tablenotes}
\small
\item * Assumed
\item \textbullet~Normalized to 1MS/s
\item $\blacklozenge$~One of the tested modes
\item \textdaggerdbl~Needs 2 exterior passive components
\end{tablenotes}
\end{threeparttable}
\end{table}
\end{document}

答案1
在标题单元格中引入换行符、不将单元加粗以及消除表格左右边缘不需要的空白，使得表格材料适合文本块。
既然您正在使用该软件包，那么请养成正确threeparttable使用它的机器的习惯。\tnote
（以下问题中的问号是因为\cite无法解决指令而出现的。）

答案2
与 Mico 的答案类似，但对于列标题，我建议使用包thead中的makecell选项，对于第一列使用选项>{\bfseries}：
编辑：
第一次尝试时，表格仍然溢出到右侧。可以使用以下方法获得等于文本宽度的表格宽度，\begin{tabular*}{\linewidth}{...}然后设置列分隔@{\extracolsep{\fill}}：
\documentclass{article}
\usepackage{booktabs, makecell, threeparttable}
\renewcommand\theadfont{\bfseries\normalsize}
\usepackage{amssymb}
\usepackage{showframe}% for shoe page layout, in real application had to be deleted
\renewcommand*\ShowFrameColor{\color{red}}
\begin{document}
\begin{table}[ht]
\caption{Synthesizable circuits summary.}
\label{tab:summary}
\setlength\tabcolsep{3pt}
\centering
\begin{threeparttable}
\begin{tabular*}{\linewidth}{@{\extracolsep{\fill}}>{\bfseries}lccccc}
