rmarkdown 表的单个单元格中的多行 [英] Multiple lines in a single cell for rmarkdown table

问题描述

我想使用 RMarkdown 创建一个在单个单元格中有多行的表格.此页面提到了多行和网格表格单元格 (http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html).但似乎反斜杠不起作用.

I would like to create a table which has multiple lines in a single cell using RMarkdown. This page mentions multiline and grid table cells (http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html). But it seems backslash is not working.

A backslash followed by a newline is also a hard line break. 
Note: in multiline and grid table cells, this is the only way 
to create a hard line break, since trailing spaces in the cells are ignored.

这是我的示例 Rmd 文件.

This is my example Rmd file.

---
title: "Test"
author: "test"
date: "Tuesday, November 25, 2014"
output: html_document
---
Line 1 \  Line2  | Line 1 \  Line2
------------- | -------------
Line 1 \  Line2 | Line 1 \  Line2

是否有可能实现这一目标?感谢您的任何建议.

Is it possible to achieve this? Thanks for any suggestions.

推荐答案

这是绝对可行的，参见 pander.CrossTable 使用这种方法:

It's absolutely doable, see eg pander.CrossTable using this approach:

> pander::pander(descr::CrossTable(mtcars$am, mtcars$gear))
