title: css table misaligning the second column when placing the scroll bar
body: <p>This only happens when I put the scroll bar in the body of the table.
  my code:</p>
  <pre><code>.fixroll-thead, .fixarrolagem-tbody { 
    display: block;  
  }
  .fixroll-tbody {
      height: 28rem;
      overflow-y: auto;
      width:100%;
      float: left;        
  }
  </code></pre>
