我正在尝试对齐此表中的数字，以便小数点始终位于彼此下方。这似乎适用于 siunitx 包。但是，我遇到了两个困难：
第二列中负数的小数点（尽管小数点确实显示在倒数第二列）。
尽管我没有在代码中的小数点前添加 0，但表格在编译后仍显示零。我该如何摆脱这个问题？
非常感谢你的帮助！

答案1
您的数字可能有一个减号，整数部分有一位数字，小数部分有两位数字，因此规范如下
S[table-format=-1.2]
S[table-format=1.2]
分别。我将使用您放置在表格顶部的文本的标题并删除第一列中的句点。
由于 a\tnote使用零宽度，我稍微放大了\tabcolsep。我觉得\footnotesize没有必要，所以我把它注释掉了。
注意前导零是这是一种很好的做法，而忽略它则不是。

你可能使用选项删除小数点分隔符前的零
print-zero-integer=false
\sisetup你会得到

编辑： 已考虑 OP 评论。现在十进制数没有前导整数零。
您可能喜欢以下表格格式：
它是通过使用 tabularray包来设置的：
