表格中的公式超出了页面的范围

我查看了几个有关超出页面的表格的主题。我添加到前面主题的问题是，我使用的是方程式而不是文本。当我尝试缩短下标时，它会将方程式向前移动到边缘而不是将其置于内部中心。有没有办法规范化表格中的内容以使其适合页面？

\begin{table}[h]
    \centering
    \begin{tabular} {SS, |1|p{0.8\linewidth}|}   
    \toprule 
    Node & Thermal balance equation \\ 
    \midrule
   1           &$-\frac{k_{glass}~N_{sub}}{D_{glass}} \cdot     (T_1-T_2)-h_{Conv-top}(T_1-T_{Ambient})-h_{Rad-top-sky}(T_1-T_{sky})-h_{Rad-top-ground} (T_1-T_{ground})=0$ \\
   2       & $Q_{glass}+\frac{k_{glass}N_{sub}}{D_{glass}} (T_1-T_2)-\frac{k_{glass}N_{sub}}{D_{glass}} (T_2-T_3)=0$    \\
    3      & $Q_{glass}+\frac{k_{glass}N_{sub}}{D_{glass}} (T_2-T_3)-\frac{k_{glass}N_{sub}}{D_{glass}} (T_3-T_4)=0$   \\
    4-10    & \vdots    \\ 
    11       & $-\frac{k_{Backsheet}~N_{sub}}{D_{Backsheet}} \cdot     (T_{10}-T_{11})-h_{Conv-bottom}(T_{11}-T_{Ambient})-h_{Rad-bottom-sky}(T_{11}-T_{sky})-h_{Rad-bottom-ground} (T_{11}-T_{ground})=0$    \\ 
    \bottomrule
\end{tabular}
    \caption{Thermal properties of each layers}
    \label{tab: 3-1}
\end{table}

我建议您采用tabularx占据文本块整个宽度并允许自动换行的环境。

在此处输入图片描述

\documentclass{article}
\usepackage{tabularx,array,booktabs}
\newcolumntype{Q}{>{\raggedright\arraybackslash$\displaystyle}X<{$}}
\newcommand{\vn}[1]{\mathrm{#1}}
\begin{document}
\begin{table}[h]
    %\centering
    \begin{tabularx}{\textwidth}{@{} l Q @{}}
    \toprule
    Node & $Thermal balance equation$ \\
    \midrule
    1&-\frac{k_{\vn{glass}}~N_{\vn{sub}}}{D_{\vn{glass}}} \cdot (T_1-T_2)-h_{\vn{Conv}-\vn{top}}
    (T_1-T_{\vn{Ambient}})
    -h_{\vn{Rad}-\vn{top}-\vn{sky}}(T_1-T_{\vn{sky}})
    -h_{\vn{Rad}-\vn{top}-\vn{ground}} (T_1-T_{\vn{ground}})=0 \\
    2 & Q_{\vn{glass}}+\frac{k_{\vn{glass}}N_{\vn{sub}}}{D_{\vn{glass}}} (T_1-T_2)
        -\frac{k_{\vn{glass}}N_{\vn{sub}}}{D_{\vn{glass}}} (T_2-T_3)=0    \\
    3 & Q_{\vn{glass}}+\frac{k_{\vn{glass}}N_{\vn{sub}}}{D_{\vn{glass}}} (T_2-T_3)
        -\frac{k_{\vn{glass}}N_{\vn{sub}}}{D_{\vn{glass}}} (T_3-T_4)=0   \\
    4--10 & \vdots    \\
    11 & -\frac{k_{\vn{Backsheet}}~N_{\vn{sub}}}{D_{\vn{Backsheet}}} 
         \cdot (T_{10}-T_{11})-h_{\vn{Conv}-\vn{bottom}}(T_{11}-T_{\vn{Ambient}})
         -h_{\vn{Rad}-\vn{bottom}-\vn{sky}}(T_{11}-T_{\vn{sky}})
         -h_{\vn{Rad}-\vn{bottom}-\vn{ground}} (T_{11}-T_{\vn{ground}})=0    \\
    \bottomrule
\end{tabularx}
    \caption{Thermal properties of each layers}
    \label{tab:3-1}
\end{table}
\end{document}

在您的代码片段中，您有奇怪的列类型：SS,。如果我用以下方法替换它们，c我会得到：

\documentclass{article}
\usepackage{amsmath}
\usepackage{array, booktabs}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}

        \\[12pt]

    \bottomrule
\end{tabular}
    \caption{Thermal properties of each layers}
    \label{tab: 3-1}
\end{table}
\end{document}

注意：对于变量索引中的文本，我使用\textamsmath package. Also some more vertical space betwee rows in table is introduced by\makegapedcells from the packagemakecells` 中的命令。
