Latex 标题未与长表模式下的表对齐

在我的长表中，当我使用横向模式时，标题与表格宽度不对齐。虽然当我移除横向模式时，它很好。然而，我的桌子又宽又长，我需要将它与横向模式对齐。这是一个MWE，请帮帮我

谢谢

以下任一修复程序：

如下所示覆盖

\LTcapwidth

，就像您的

环境开始一样

\begin{ThreePartTable}
\begin{landscape}
\setlength\LTcapwidth{\linewidth}

...

或者，只需删除文档标题中

\LTcapwidth

的

\setlength

命令即可

% \setlength{\LTcapwidth}{\textwidth}

产生以下结果：

---

通常，对于

横向

模式，请使用

\linewidth

而不是

\textwidth

谢谢！你的解决方案1非常有效。我会记住关于横向模式的建议以及\linewidth而不是\textwidth的使用。你帮了大忙“dfri”：@shotgun很乐意帮忙！
