我正在 Overleaf 上使用以下长表：

当我的表格跨越两页时，其中一个 \hlines 会产生一条与其表格对象分离的孤立水平线：
当我尝试向下移动表格，希望 hline 能够加入其迷你表格时，我得到了重复的一行：
有没有什么方法可以让我的表（及其子组件）的行为更加统一？
下面是我的 overleaf 项目的简化版本：

希望得到一些帮助！

答案1
这是代码的一个简化版本，主要是通过删除所有\multicolumn{1}{.}{.}包装器并将longtable设置切换到table/tabular设置来实现的。我还删除了所有垂直线和大多数水平线，以便使表格看起来更加开放，并且我放弃了所有\textbf指令 —— 它们根本就不需要。最后，我还将第二组和第四组向右移动了一列。
