<h1>Grouped Header Example</h1>
<p>This example shows how to create a grid with column headers which are nested within category headers.</p>
<p>Category headers do not reference Model fields via a <code>dataIndex</code>, rather they contain
child header definitions (which may themselves either contain a <code>dataIndex</code> or more levels of headers).</p>
<p>The syntax is as simple as:<pre><code>{
header: 'Category Header',
headers: [{
header: 'First Sub Header',
dataIndex: 'subHeaderField1'
}, {
header: 'Second Sub Header',
dataIndex: 'subHeaderField2'
}]
}</code></pre>
<p>Note that the js is not minified so it is readable. See <a href="group-header-grid.js">group-header-grid.js</a>.</p>
