title: Convert a column of text URLs into active hyperlinks in Shiny
body: <p>I am creating a user interface for a pathway enrichment program. The results are shown in a table as shown below. </p>
  
  <p><img src="https://i.stack.imgur.com/NpHRZ.png" alt="enter image description here"></p>
  
  <p>Below is a snippet showing that I am using DT::renderDataTable and DT::datatable to output the table in a tab. spia_out() is just a reactive function that runs the pathway enrichment and produces a dataframe.</p>
  
  <pre><code>spia_out &lt;- reactive({
      ...get results in a dataframe...
    })
  
  output$spiaout &lt;- DT::renderDataTable({
        DT::datatable(spia_out(), extensions = ..., options = ...)
    })
  </code></pre>
  
  <p>Everything works fine, the pathway enrichment table is generated &amp; printed in the corresponding UI element. My only problem is how to convert the last column (KEGGLINK) of URLs into active hyperlinks? So that people can just click on them instead of copy &amp; pasting.</p>
  
  <p>Apologies in advance for the screenshot's size. I hope you can see the last column KEGGLINK has URLs but they are not active.</p>
