我在使用 LaTeX 表格时遇到了问题，因为它们位于多页上，尽管最大页数为两页。此外，行间距很大。我该如何调整？当上一页已满且没有任何间距时，如何让表格移动到下一页？
\newcolumntype{C}[1]{>{\centering\arraybackslash}p{#1}}
\renewcommand{\arraystretch}{0.5}
\begin{longtable}{|C{2cm}|C{2.5cm}|C{3cm}|C{2cm}|C{5cm}|}
\caption{Summarizing deep learning for medical image classification}
\label{table:ex1} \\

- 请始终提供 MWE（最小工作示例），这是一个完整的小文档，以便我们可以对其进行编译。
\textwidth当article使用文档类时，给定列的宽度总和超出了默认大小。
使用包的解决方案longtblr，tabularray其中考虑：
geometry页面布局由包定义- 最后两列的宽度相同（比前两列宽 2.3 倍）
- 用于对齐最后两列单元格中的文本的
ragged2e包 - 也用于
microtype包装以更好地实现文本的词间间距 - 为了更好地调整单元格中的文本间距，表格中的字体大小减小了（至
\small）

答案2
从一开始，如果您唯一的问题是表格高度，您可以尝试更改此特定的行...
\begin{longtable}{|C{2cm}|C{2.5cm}|C{3cm}|C{2cm}|C{5cm}|}
变成这样！
\begin{longtable}{|C{2.5cm}|C{3cm}|C{3cm}|C{3cm}|C{3cm}|}
因为，因为列类型“ C”在第一行上的定义方式，在每个 上C{x}，x控制每列文本框的宽度。如果您的项目需要总长度为 14.5 厘米，您可以使用我之前发布的行。但它的要点是修改这些值，以便较长的文本有更多可用的水平空间！
另外，您是否需要使用tabularx和longtable包来编写此文档？您可以查看tabularray包，因为它可以让您更好地控制表格。
最后，请记住，定义为“长表”的表总是会尽可能地破坏页面。如果您想避免这种情况，请在示例中使用环境tabularx。
