Example

In addition to jQuery, jQuery UI, and Fancytree, include jquery.fancytree.table.js and optionally jquery.fancytree.gridnav.js:

  <script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>
  <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1/jquery-ui.min.js" type="text/javascript"></script>
  <link href="skin-win8/ui.fancytree.css" rel="stylesheet" type="text/css">
  <script src="js/jquery.fancytree.js" type="text/javascript"></script>
  <script src="js/jquery.fancytree.gridnav.js" type="text/javascript"></script>
  <script src="js/jquery.fancytree.table.js" type="text/javascript"></script>

we also define an empty table with its headers

<table id="tree">
	<colgroup>
	<col width="30px"></col>
	<col width="30px"></col>
	<col width="*"></col>
	<col width="50px"></col>
	<col width="30px"></col>
	</colgroup>
	<thead>
		<tr> <th> </th> <th>#</th> <th></th> <th>Key</th> <th>Like</th> </tr>
	</thead>
	<tbody>
	</tbody>
</table>

The tree table extension takes care of rendering the node into one of the columns. Other columns have to be renderd in the renderColumns event:

$("#tree").fancytree({
	checkbox: true,
	titlesTabbable: true,        // Add all node titles to TAB chain
	source: SORUCE,
	extensions: ["table", "gridnav"],
	table: {
		checkboxColumnIdx: null, // render the checkboxes into the this column index (default: nodeColumnIdx)
		customStatus: false,	 // true: generate renderColumns events for status nodes
		indentation: 16,         // indent every node level by 16px
		nodeColumnIdx: 0         // render node expander, icon, and title to this column (default: #0)
	},
	gridnav: {
		autofocusInput:   false, // Focus first embedded input if node gets activated
		handleCursorKeys: true   // Allow UP/DOWN in inputs to move to prev/next node
	},

	renderColumns: function(event, data) {
		var node = data.node,
			$tdList = $(node.tr).find(">td");

		// (index #0 is rendered by fancytree by adding the checkbox)

		// 
		$tdList.eq(1)
			.text(node.getIndexHier())
			.addClass("alignRight");

		// (index #2 is rendered by fancytree)
		// Make the title cell span the remaining columns, if it is a folder:
		if( node.isFolder() ) {
			$tdList.eq(2)
				.prop("colspan", 3)
				.nextAll().remove();
			return;
		}
		// ...otherwise render remaining columns

		$tdList.eq(3).text(node.data.myCustomData);
		$tdList.eq(4).html("<input type='checkbox' value='" + node.key + "'>");
	}
});
