我想按以下方式对齐我的表格：
砷______0,63+-0,12__________18 +-12
砷________11,7+-0,6__________109 +-9
正如您所看到的，我不希望 \pm 符号和数字之间有任何空格，即使某些数字有小数（后者应该被完全忽略）
我该如何使用我的表来实现这一点？我无法使用 sinunitx 完成这项工作。

谢谢你！
答案1
这是一个采用列包。它利用了以下事实：所讨论的四列中没有.（点，又称句号）符号（除了指令中\cellcolor）。我已将所有实例转换为\pm，.并定义了一种新的列类型，d它将实例转换.回\pm。这样，列的内容将以\pm符号为中心。
