Quarto生成PDF时标题页后首页底部边距过大问题

问题描述 #

我在RStudio中使用Quarto生成PDF文档，通过quarto_titlepages扩展制作标题页。标题页之后的正文首页出现了异常大的底部边距（顶部边距正常），推测是标题页的配置残留导致的。

我尝试在pdf格式配置中设置margin-left、margin-right、margin-bottom、margin-top参数，也试过用geometry参数调整，但都没有效果。

初始效果 #

标题页后的正文首页底部空白明显过大，边距异常。

更新尝试 #

按照建议添加\\restoregeometry后，边距问题有所缓解，但pdf配置下的其他格式设置失效。于是我删除了独立的pdf层级，将所有PDF相关配置移到titlepage-pdf下，然而首页底部边距过大的问题再次出现，即使保留了\\restoregeometry命令。

更新后的配置代码 #
