title: How can I add a blank editable row with Ant Design table?
body: <p>Trying to create an "Add Row" button that results in a new fillable/editable row added to the table. The issue is, when I have the editable fields be empty strings, the edit field does not display and thus the user cannot change the contents of it:</p>
  
  <pre><code>// RESULTS IN NO FIELD DISPLAYED
  const newCategoryRow = {
      key: 'NEW',
      acct: '',
      description: '',
      total: 0
  }
  
  // RESULTS IN FIELD DISPLAYED
  const newCategoryRow = {
      key: 'NEW',
      acct: 'blah',
      description: 'blah',
      total: 0
  }
  </code></pre>
  
  <p>Any way to do this?</p>
