title: NatTable: How can you access column header of a particular column?
body: <p>In the example below,</p>
  <pre class="lang-java prettyprint-override"><code>configRegistry.registerConfigAttribute(
                  CellConfigAttributes.CELL_PAINTER,
                  new BeveledBorderDecorator(
                          new VerticalTextPainter(false, true, true)),
                  DisplayMode.NORMAL,
                  GridRegion.COLUMN_HEADER);
  </code></pre>
  <p>the column header text is vertically aligned, how can I apply this styling to a particular column instead of all columns, Looking for guidance.
  Thanks in advance</p>
