我上个月学习了 Latex，并尝试用它编写一个大型文档。我已经管理了文本和图片，但没有表格。虽然我的表格居中，但我希望标题与表格的第一个单元格一起开始，而不是像普通段落那样完全左缩进。
我还有许多脚注，它们与整个表格有关，而不是表格的特定部分。我尝试使用 \tablefootnote，但似乎没有出现任何文本。另外，我不需要数字，只想要文本。

我尝试变得聪明一些，但是第二个标题没有奏效：
\begin{table}[h!]
\begin{center}
\caption{Proximate phenolic and carbohydrate content}
\label{Table4}
\begin{tabular}{c c c c c c c}
\toprule
&\multicolumn{2}{c}{\textbf{Leaf}}& &\multicolumn{2}{c}{\textbf{Roots}}\\

\textbf{Plant} & \textbf{Colour} & \textbf{Density} & &\textbf{Colour} & \textbf{Density}\\
\midrule
Sample1&26.1$\pm$0.7$^{c}$ &172.3$\pm$9.0& & 25.5$\pm$6.8$^{b}$&83.7$\pm$4.5$^{a}$\\
Sample2&53.9$\pm$2.0$^{d}$&129.5$\pm$3.2& &29.4$\pm$4.8$^{b}$&11.7$\pm$1.8\\
Sample3&32.5$\pm$3.2$^{c}$&163.3$\pm$6.5& &96.8$\pm$18.1&64.4$\pm$1.3\\

\end{tabular}
\end{center}
\begin{tabular}
\footnotesize{Values expressed in \%(mg.mg$^{-1}$)}\\
\footnotesize{Values with same superscript are statistically similar (OW-ANOVA,p \textless 0.01)}\\

\end{table}
这个解决方案在横向格式下有效吗？我也有这种类型的表格
答案1
这是我建议用于threeparttable表格注释的。标题对齐也是threeparttable结合适当的来完成的captionsetup。为了改善表格中数字的对齐，我添加了siunitx包：
