title: Is it possible to have expressions in dplyr tibbles?
body: <p>I'm using <code>dplyr</code>, <code>kabble</code>, and <code>kableextra</code> to create some tables in R. I'm converting the <code>tibble</code> outputs from <code>dpylr</code> chains for tables in a report. I'd like to have the rank included as a column in a <code>tibble</code> that I then pipe into a <code>kabble</code> table. Is there a way to do this using mark-up or perhaps an R package that has the numeric expressions for ranks (i.e., 1st, 2nd, 3rd)? </p>
  
  <p>I've tried this, but with many ranks it is impractical. Something similar to <code>LETTERS</code> would be good. </p>
  
  <pre><code>expression('1^st')
  expression('2^nd')
  </code></pre>
