如何删除标题和表格之间的空白? [英] How do you remove white space between title and table?

问题描述

我也尝试在其他地方询问此问题，但是我无法删除表格标题和实际表格之间的空白.在我的常规rmarkdown文章中，不会发生这种情况，但是当我为演示文稿而扎弯时，它会产生这些奇怪的空白.有人知道为什么吗?

I tried asking this somewhere else as well, but I am having trouble removing the white space between the title of my table and the actual table. This doesn't happen when in my regular rmarkdown article, but when I knit to beamer for my presentation it produces these bizarre white spaces. Anyone know why?

mean.party.class <- dat3 %>%
  group_by(party2, class2) %>%
   filter (party2 !="Indep" & class != "IDK")%>%
  summarise_at(vars(DL, DU, RL, RU, L, U, D, R), funs(mean(., na.rm=TRUE)))

knitr::kable(mean.party.class, col.names=c("Party ID", "Class", "DL", "DU", "RL",   "RU",   "L", "U", "D" , "R"), digits=2,  caption = "Mean Trust Per Group (Party and Social Class Identity)", "latex", booktabs = T) %>%
 kable_styling( full_width = F, position = "left",  latex_options = "scale_down", bootstrap_options = c("striped", "hover")) %>% footnote(
   general = c("1. D= Democrat, R=Republican, L=Lower Class, U = Upper Class; ", "2. Independents dropped")) %>% row_spec(0,bold=TRUE)

这里是一个示例

推荐答案

如果在标题中添加 keep_tex:true ，则可以编辑生成的.tex文件，以消除造成多余空间的多种原因:

If you add keep_tex: true to your header you can edit the resulting .tex file to remove the multiple causes of the additional space:

• 删除桌子周围不必要的且通常有害的 \ resizebox {\ linewidth} {！} {...}

删除 caption 程序包(该程序不必要地多次加载)

remove the caption package (which is unnecessarily loaded multiple times)

删除 parskip 包

(我会远离 tabu ，而使用普通表)

(I would stay away from tabu and use a normal table instead)
