title: How to add specific style to GWT DataGrid
body: <p>I need add new style for some DataGrid rows, depending on variable.</p>
  
  <p>For example:</p>
  
  <pre><code>table.setRowStyles(new RowStyles&lt;Entry&gt;() {
      @Override
      public String getStyleNames(Entry entry, int rowIndex) {
          return entry.isStyle() ? "newStyle" : null;
      }
  });
  </code></pre>
  
  <p>"newStyle" is global css style.</p>
  
  <p>The problem is style not applied to rows until i add <code>!important</code> to css definition.
  But with <code>!important</code> i lost all default DataGrid styles and have only "newStyle".</p>
  
  <p><strong>UPDATE:</strong> css file</p>
  
  <pre><code>.newStyle {
      color : lightgray;
  }
  </code></pre>
