使用rmarkdown生成的投影仪演示文稿中列的内容垂直居中对齐 [英] Vertically center-align content of columns in a beamer presentation generated with rmarkdown

问题描述

如何在rmarkdown :: beamer_presentation中垂直对齐多列的内容?

如对

如果有一种简单的方法可以为每一列以不同的方式对齐内容，那也将非常有用(例如，c1:顶部，c2:中间，c3:底部，c4:中间)

解决方案

您可以使用 :::: {.columns align = center} 来获取中心对齐

How to vertically center-align the content of multiple columns in a `rmarkdown::beamer_presentation?

As recommended in a comment in to an answer to this SO post, I tried ::: {.column width="30%"}, which however did not work for me.

If there is a simple way to align content differently for each column, that would further be very helpful too (e.g., c1: top, c2: middle, c3: bottom, c4: middle).

解决方案

You can use :::: {.columns align=center} to get centre alignment
