title: Conditional formatting cell in DataTable in R
body: <p>I have the following code so far as an example:</p>
  
  <pre><code>library(DT)
  
  datatable(iris, options = list(pageLength = 5)) %&gt;%
    formatStyle(
      'Sepal.Width',
      backgroundColor = styleInterval(3, c('gray', 'yellow'))
  )
  </code></pre>
  
  <p>I am interested though in highlighting only a specific "cell" based on a condition.</p>
  
  <p>For example if <code>iris[3, 2] &gt; 3.1</code> then background colour should be yellow.</p>
  
  <p>for reference <a href="http://rstudio.github.io/DT/" rel="noreferrer">http://rstudio.github.io/DT/</a></p>
  
  <p><code>sessionInfo()</code> <code>DT_0.1</code></p>
