latex设置文本宽度和表格宽度一样

可以使用`\resizebox`命令将文本框缩放到与表格宽度相同的大小。具体操作步骤如下：

1. 在导言区添加`\usepackage{graphicx}`，调用该包。

2. 在文本框前后分别添加`\resizebox{\linewidth}{!}{...}`命令，其中`\linewidth`表示文本框宽度为行宽，`!`表示高度按比例自适应。

例如，以下代码将文本框宽度设置为表格宽度，并使文本框内容居中对齐：

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{tabular}{|c|c|}
\hline
Title 1 & Title 2 \\
\hline
\resizebox{\linewidth}{!}{%
    \centering
    Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here. Some text here.%
} \\
\hline
\end{tabular}
\end{document}

注意，`\resizebox`命令会按比例缩放文本框的内容，因此可能会影响排版效果。如果需要保持原来的字号和行距，请考虑其他方法，例如自定义表格列格式或使用`\parbox`命令。
