第一列的 Longtable 缩进

tag-icon • tag-icon line-breaking longtable alignment
第一列的 Longtable 缩进

我无法使长表第一列的文本正确对齐。

问题是，在换行符（自动）之后，文本会缩进。更像是反向缩进，因为它比第一行更靠左对齐。我想避免这种情况，但找不到可行的解决方案。在过去的三个小时里，我尝试通过 \newcolumntype 和其他一些东西进行重新定义，现在我正式放弃了 :D 希望有人能帮忙。

这是我的 MWE，其中奇怪的对齐发生在第一行：

关于rules在您的表格中使用的，请阅读我在您的问题下面的评论。

编辑： 添加了表头、末头、表尾和末尾的代码。略微减少了\arraystreatch（行变得更紧凑）并增加了单元格中的垂直空间。现在行更加清晰可见，并且行与行之间不再使用线条。

摆脱神秘的\rule[-1ex]{0pt}{2.5ex}指令是一个很好的第一步。如果你仔细观察，你会发现longtable比文本块更宽；有必要减少一些列宽。另外，请将所有三列从完全对齐更改为右对齐布局。
