<h1>DataTable Control: Custom Cell Formatting</h1>
<div class="exampleIntro">
<p>This example demonstrates a variety of ways to format data in a DataTable,
including form elements, dates, currency, email addresses, and links. The first
Column displays custom UI that is based on data in another Column and uses classes to highlight its cells green or red.</p>
