title: semantic-ui-react <Responsive> not working for <Table.Cell>
body: <p>I am using semantic-ui react to render a table of data. My requirement is that when the page is on mobile view, I hide certain columns. I tried using <code>className="mobile hidden"</code> on the <code>Table.Cell</code> element but this doesn't seem to work at all. </p>
  
  <p>Then I tried using the <code>Responsive</code> component like below but I am getting an error. Am I missing something here? Unable to find anyone else having this issue ...</p>
  
  <pre><code>  &lt;Responsive as={Table.Cell} minWidth={Responsive.onlyMobile.minWidth}&gt;
       {record.datapoint}
    &lt;/Responsive&gt;
  </code></pre>
  
  <p>I get this error in the console when resizing the window...</p>
  
  <pre><code>index.js:2177 Warning: Can only update a mounted or mounting component. This usually means you called setState, replaceState, or forceUpdate on an unmounted component. This is a no-op.
  
  Please check the code for the Responsive component.
