在使用 rmarkdown 生成的投影仪演示文稿中垂直居中对齐列的内容

问题描述

如何在`rmarkdown::beamer_presentation 中垂直居中对齐多列的内容？

正如对 this SO post 的回答的评论中所建议的那样，我尝试了 ::: {.column width="30%"}，但它对我不起作用。

如果有一种简单的方法可以针对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） .

:::: {.column width="30%"}
```{r top-p-5,echo=FALSE,out.width='30%'}
plot(pressure[1:5,])
```

:::: {.column width="30%"}
```{r top-p-10,out.width='50%'}
plot(pressure[1:10,])
```
::::

:::: {.column width="30%"}
```{r top-p-all,out.width='100%'}
plot(pressure[1:nrow(pressure),])
```

## figures in columns center-aligned (not working)
::: columns

::: {.column width="30%"}
```{r center-p-5,])
```
:::

::: {.column width="30%"}
```{r center-p-10,])
```
:::

::: {.column width="30%"}
```{r center-p-all,])
```

解决方法

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

为了补充来自@samcarter_is_at_topanswers.xyz 的有用答案，可以采用以下方法来以不同方式对齐每列中的内容：

    slide_level: 2
    keep_tex: true

```{r echo=FALSE}
# CHECK PANDOC VERSION
library(rmarkdown)
if (pandoc_available())
  cat("pandoc",as.character(pandoc_version()),"is available\n (pandoc >2.11.2 is required)")
```

## Figures in columns center-aligned (set for all columns at once)
:::: {.columns align=center}

::: {.column width="30%"}
```{r center-p-5,])
```
:::

::::


## Figures in columns aligned differently (set for separately for each column)
:::: {.columns}

::: {.column width="30%" align=center}
center
```{r 3-center-p-5,])
```
:::

::: {.column width="30%" align=top}
top
```{r 3-top-p-10,])
```
:::

::: {.column width="30%" align=bottom}
bottom
```{r 3-bottom-p-all,])
```
