# 我該如何變更 LaTeX 表格中的欄間距或列間距？

一種選擇是使用指令 `\setlength` 和 `\arraystretch` 分別用來改變水平間距（欄間距）與垂直間距（列間距）；例如：

```latex
\setlength{\tabcolsep}{20pt}
\renewcommand{\arraystretch}{1.5}
```

以下範例可直接在 Overleaf 中開啟，展示了以下指令的使用： `\setlength` 和 `\arraystretch` 間距。

```latex
\documentclass{article}
\begin{document}

\section*{Table with default spacing}

% 一個具有預設列與欄間距的表格
\begin{tabular}{ l c c }
First Row & 6 & 5 \\
Second Row & 4 & 10\\
Third Row & 20 & 30\\
Fourth Row & 100 & 30\\
\end{tabular}

\section*{Table with adjusted spacing}

% 一個已調整列與欄間距的表格。

% \setlength 設定水平（欄）間距
% \arraystretch 設定垂直（列）間距

\begingroup

\setlength{\tabcolsep}{10pt} % 預設值：6pt
\renewcommand{\arraystretch}{1.5} % 預設值：1
\begin{tabular}{ l c c }
First Row & 6 & 5 \\
Second Row & 4 & 10\\
Third Row & 20 & 30\\
Fourth Row & 100 & 30\\
\end{tabular}

\endgroup
% \begingroup ... \endgroup 配對可確保間距值
% 參數只會影響這個表格，而不影響任何
% 文件中的後續表格。
\end{document}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-da/25-how-do-i-change-column-or-row-separation-in-latex-tables.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
