<h1>Showing, Hiding, and Reordering Columns</h1>
<p>This example uses the Dialog and Button widgets to interactively show and hide Columns. Columns are also reorderable via built-in integration with the Drag and Drop Utility.</p>

<span class="corner_tl"></span>
<span class="corner_br"></span>
<span class="corner_bl"></span>
<div class="hd">
