这就是 latex 代码。我的问题是，最右边的两列没有在符号上对齐\times（因为有负数）。我怎样才能强制它沿着符号对齐\times？

您可能喜欢以下解决方案：

编辑：

  • 因为所有列都使用了S列类型，因此\num{...}表体中的所有内容都被删除
  • 删除所有垂直线
  • 对于水平线，使用booktabs包中定义的规则
  • 为了提高可读性，每隔一行后插入一个小的垂直空格\addlinespace

如您所见，数字与小数点完全对齐，并且所有数字在指数标记处都有相同的小数位数。

附录使用新颖的表格包 `tabularray`` 可以实现非常相似的结果。使用它会自动插入垂直间距：
