我想创建一个带有变量描述的表格。首先，下面显示的表格字体非常小，文本没有换行。其次，我需要让表格继续在下一页。我该如何解决这些问题？
\begin{table}[!htbp]
\fontsize{11}{9}\selectfont
\caption{Description of Variables used in this Study}
\label{table: vardescription}
\begin{center}
\begin{tabular}{ l | p{13cm} }
\hline \hline
\textbf{\normalsize Code} & \textbf{\normalsize Definition and source} \\
\hline
\textbf{exportsgr} & Exports of goods and services (annual \% growth) retrieved from World Bank. \\ \hline
\textbf{importsgr} & Imports of goods and services (annual \% growth) retrieved from World Bank.\\ \hline
\textbf{gr\_tot} & Terms of trade change over previous year (in \%). Data for terms of trade are collected from theglobaleconomy.com and Kaminsky and Reinhart online database. Since variables have two different base years, the base year for both was changed to 2000 to have the same base year. And then the change is calculated as below.
\begin{equation}
gr\_tot_{i,t} = (\frac{tot_{i,t}- tot_{i,t-1}}{tot_{i,t-1}})100
\end{equation}
\\ \hline
