In addition to the above code, the following Javascript library files are loaded for use in this example:

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

				<table id="sites" class="display">
					<thead>
						<tr>
							<th>Name</th>
							<th>Users</th>
						</tr>
					</thead>
				</table>
				<table id="users" class="display">
					<thead>
						<tr>
							<th>First name</th>
							<th>Last name</th>
							<th>Phone #</th>
							<th>Location</th>
						</tr>
					</thead>
				</table>

Editor submits and retrieves information by Ajax requests. The two blocks below show the data that Editor submits and receives, to and from the server. This is updated live as you interact with Editor so you can see what is submitted.

Submitted data:

The following shows the data that has been submitted to the server when a request is made to add, edit or delete data from the table.

// No data yet submitted

Server response:

The following shows the data that has been returned by the server in response to the data submitted on the left and is then acted upon.

// No data yet received
