编译后我得到了
我不知道如何编辑它。请帮忙。

我建议使用以下示例：
\documentclass[12pt]{article}
\usepackage[paperheight=13in,paperwidth=8.5in,top=1in,left=1.5in,right=1in,bottom=1in]{geometry}
\usepackage{lscape}
\usepackage{makecell}
\usepackage{tabularx}
\usepackage{booktabs}
\begin{document}
\begin{landscape}
\begin{table}[htbp]
\begin{tabularx}{\linewidth}{lXcc}
Proponents & \textbf{Study} & \textbf{Date Completed/Published} & \textbf{Collaborationg Agency} \\
\midrule
\makecell[tl]{Berlita Y. Disca \\ Edgar Mabad} & Programs on Drug and Substance Abuse Prevention and Law Enforcement in Two Cities in Region 12: An Empirical Study & August 2017 & DOST-PCRD Region12\\
\midrule
\makecell[tl]{Leonida, Rene E. \\ Dela Cruz, Rendon A. \\ Aujero, Emmylou M. \\ Deleverio, Marchelle A. \\ Bodegas, Nimfa L.}& Secure Weakly Connected Domination in the Join of Graphs & March 2015 &HIKARI Ltd.\\
\end{tabularx}
\end{table}
\end{landscape}
\end{document}
我已使用该包tabularx将其灵活宽度的列用作X表格的第二列。表格本身的宽度与当前行宽相同。列X的宽度现在是行宽-宽度（列 1）-宽度（列 3）-宽度（列 4），其中的长行会自动断开。
为了实现第一列的格式化，我使用了makecell包来在单元格内引入换行符\\。
最后，我使用了包booktabs及其命令\midrule。此外，我还删除了表格中的所有垂直线，因为大多数情况下，它们对于理解表格来说并不是必需的
