答案1
几点：
使用
booktabs包装以获得更好的间距使用
siunitx包来正确获取值和单位之间的空间使用
tabularx将表格保持在可用的文本宽度内，你的表格要宽得多细分中间规则
您的参数似乎是一些变量的名称？我会用打字机字体或小写字母来写它们。
将列左对齐。在非常窄的列中对齐文本永远不会看起来好看
如果单位是使用值的参数名称的一部分，则可以混合使用。我不了解你的程序，所以不知道正确的方法是什么，但要保持一致
使用以下方法使表格内容与规则对齐

答案2
这里有一个与 @samcarter 发布的解决方案非常相似的解决方案。例如，它使用环境tabularx，不完全对齐单元格内容，并使用包的宏num、\si和来显示数字、科学单位以及数字和相关单位的组合。\SIsiunitx
一些差异：
- 第 3 列不允许换行
- 第 1 列和第 2 列单元格内容的自动悬挂缩进
- 标题单元格无粗体显示
- 第 4 列中的语言更加简洁
- 使用
\path宏（由url包提供）排版文件名 - 使用
,（逗号）作为 4 位或更多位数字的千位分隔符

答案3
这是一个稍微偏离主题的答案，因为其他人已经比我更好地介绍了 TeX 方面，而我专注于写作。
您可以在最后一列中缩减许多条目的措辞。许多条目开头的“It”绝对是多余的。我还会删除“determines”或“defines”和“the”。您还可以删除其他一些冠词，并将文本编辑成更短的形式。我已经为您试过了，见下文。在某些情况下我可能做得过头了，但我仍然认为第一个条目有点冗长。这可以在除一个多行项目之外的所有多行项目中节省一行，使所有内容更易于阅读。此外，您在某些条目上有句号，但在其他条目上没有。
我还会在行之间添加一些垂直空间（在编辑过程中总高度仍然可以更小），以使最后一列更易于阅读。使用\raggedright分行而不是连字符，我已将“继续计算”用于分行，但未将“时间间隔”作为开始的单元格用于分行，以演示效果。这些要点已在其他答案中介绍，我已不一致地演示了它们\raggedright的用法。\texttt
尤其应该避免变量名中的换行符等
