\toprule 的问题：有时不加粗

我正在使用包 booktabs 并使用 \toprule、\bottomrule 等来制作粗体线条。

问题是，有时使用 \toprule 或 \bottomrule，绘制的线条会变粗，但有时却不会！不会出现错误消息，只是线条不加粗。例如下表：

\begin{table}[H]
\caption{Placebo DID: 1999-2000}
\label{placebo}

\

\centering

\begin{adjustbox}{ max width=\textwidth}

\begin{tabular}{lccc} \toprule

 & A & B & C \\

& Participation Decision (Save) & Participation Decision (Save) & Participation Decision (Save) \\

 &  &Males  & Females  \\ \cmidrule(lr{.75em}){2-4}

 &  &  &  \\

After & 0.0286** & 0.0261** & 0.0285** \\

 & (0.0125) & (0.0115) & (0.0125) \\

Region & 0.00125 & -0.00479 & -0.000551 \\

 & (0.0195) & (0.0172) & (0.0195) \\

Treatment & 0.0343 & 0.0351 & 0.0345 \\

 & (0.0273) & (0.0244) & (0.0273) \\

Female & 0.0836*** &  &  \\

 & (0.0116) &  &  \\

Female (After) & -0.00238 &  &  \\

 & (0.0156) &  &  \\
Female (Scotland) & -0.00733 &  &  \\

 & (0.0239) &  &  \\

Female (Treat) & 0.000399 &  &  \\

 & (0.0336) &  &  \\

Constant & 0.395*** & 0.446*** & 0.461*** \\

 & (0.0568) & (0.0792) & (0.0811) \\

 **&  &  &  \\ \midrule**          

Observations & 15,264 & 8,393 & 6,871 \\

 R-squared & 0.111 & 0.102 & 0.131 \\ \bottomrule

\multicolumn{4}{c}{ Robust standard errors in parentheses} \\

\multicolumn{4}{c}{ *** p$<$0.01, ** p$<$0.05, * p$<$0.1} \\

\multicolumn{4}{c}{ Source: BHPS(2009)} \\

\end{tabular}

\end{adjustbox}
\end{table}

如果我在那里设置 midrule，\toprule 和 \bottomrule 的行就不再是粗体了。相反，如果我写 \hline 而不是 \midrule，那么两行都是粗体。如果我将最大文本宽度从 0.75 更改为 0.9，也会发生同样的事情！我真的不明白！！！

感谢您的帮助！：）

您的示例运行良好。您应该放大以查看线条的正确渲染。有时，查看器无法处理所有尺寸。特别是当您使用一些缩放时。我不建议缩放表格，而是重新格式化以适合页面。请参阅以下我的建议：
