Client side templating capabilities are based on jQuery Tmpl
Templates are HTML fragments. You must not provide a full HTML file, with a <html>, <header> or <body> tag. All you need is to provide a single root element (a div for example):
<div>
<table>...</table>
<form>...</form>
...
</div>
jQuery tmpl is builtin with RESThub JS, for more features and syntax documentation see Jquery Tmpl web site
