我有几个问题：
- 目前，所有内容都是居中对齐的，因此文本包含太多空格，而不是左对齐且紧密
- 我想让整个表格自动换行。目前，我将每列的所有内容限制为 3cm，但实际上我想将整个表格限制为页面的最大宽度（如果这是某个地方的变量？）并自动换行。
- 我的表格并没有像我想象的那样溢出页面
longtable。如果我删除table长表格中的换行符，我无法指定[!ht]我的表格是否会出现在页面的某个随机位置。
我该如何解决这个问题？
答案1
让我们来检验一下你的说法：
目前，所有内容都是居中对齐的，因此文本包含太多空格，而不是左对齐且紧密
这种说法是不正确的。您确实指定了L列类型（您已将其定义为居中设置其内容），但随后您通过\multicolumn{1}{|m{3cm}|}{...}包装器覆盖了此设置。m列类型完全对齐其内容。您在屏幕截图中看到的不是居中文本，而是完全对齐的文本，其中许多单词之间有较大的“空洞”。
要获得不规则的格式，可以使用
\multicolumn{1}{|>{\raggedright\arraybackslash}m{3cm}|}{...}
包装器或者完全删除包装器并在列类型的定义中\centering替换。\raggedrightL
...我想限制整个表格的最大宽度为页面的宽度（如果这是某个地方的变量？）并且自动换行
你看过文本表环境？请与环境结合使用longtable。
我的表格没有像我以为的 longtable 那样溢出页面。如果我删除 longtable 中的表格换行符，则无法指定 [!ht]，因此我的表格将出现在页面的某个随机部分。
longtable浮动环境的前提是错误的。事实并非如此。为什么[ht!]在应用于 a 时没有效果的原因longtable是 alongtable总是从输入流中遇到的位置开始。因此：绝不将 a 包裹longtable在 a 里面table。永远、永远。无论如何都不可能。
以下是我重新编写代码的方法。请注意，我重新组织了内部材料，longtable以便更清楚地区分表头、表脚和表体。我还删除了所有垂直线。

答案2
是longtable不是一个浮点数，因此你不能使用该table环境。
我提出了两种解决方案，基于， 将ltablex的功能引入。一种解决方案使用垂直和水平线，另一种解决方案使用 的规则，没有垂直线：longtabletabularxbooktabs
