![垂直对齐“Bigdelim”分隔符](https://linux22.com/image/461347/%E5%9E%82%E7%9B%B4%E5%AF%B9%E9%BD%90%E2%80%9CBigdelim%E2%80%9D%E5%88%86%E9%9A%94%E7%AC%A6.png)
我有一张表,我想使用 Bigdelim 包关联一些条目。但是,我不知道如何让分隔符对齐。我有一张表,碰巧每个单元格都有相同的条目,因此分隔符排列得很好:
我目前的代码如下所示:

有人知道我该如何垂直对齐表 1 中的括号,使它们看起来像表 2 吗?另外,有没有办法对齐所有不同的 A1?我刚注意到括号已将顶部两个推离了对齐位置……
(顺便问一下,有没有什么办法可以让括号之间的距离稍微分开一点?如果可能的话,我宁愿它们在表 2 中不要互相接触,但这只是一种风格偏好......)

具有{NiceTabular}

siunitx
d
dcolumn

在 中nicematrix
,有一个内置命令\SubMatrix
可用于绘制括号。

与往常一样nicematrix
,您需要进行多次编译。
在 中{NiceTabular}
,无法定义同时具有X
和S
(的siunitx
)列特征的列。但是,可以使用。该环境对应于标准 LaTeX 的{NiceTabular*}
环境。{tabular*}
