title: How to change fontface (bold/italics) for a cell in a kable table in rmarkdown?
body: <p>Is there a way to format a single cell in a table in rmarkdown? I am using kable to generate a table as follows:</p>
  
  <pre><code>library(knitr)
  kable(data.frame(c('a','b','c'),c(1,2,3)))
  </code></pre>
  
  <p>I wish to bold "c" in the last row and also add a horizontal line at the end of the table. Any pointers?</p>
