我想创建一个使用RMarkdown在单个单元格中有多行的表。此页面提到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。
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。

title: "Test"
author: "test"
date: "Tuesday, November 25, 2014"
output: html_document

Line 1 \ Line2 | Line 1 \ Line2
------------- | -------------
Line 1 \ Line2 | Line 1 \ Line2
有可能实现这一目标吗？谢谢你的任何建议。
