title: How can i set a row in a gt table to be a specific color
body: <p>So, for example in the table below, I want to make the background color for the third row #D9654B.
   It can be done either by specifying the third row or making it conditional on V1=="c"</p>
  
  <pre><code>
  df &lt;- tibble(V1=c("a","b","c"),V2=c(7:9))
  df %&gt;% 
    gt()
  </code></pre>
