Paging the rows

You can limit the number of visible rows with the max method. If the table contains more rows, a Pager will be created. An equivalent method size also fixes the height of the Table so that the pager (footer) never jump up and down.

```
$.getJSON('assets/rowdata.json', function(json) {
	ts.ui.get('#example9', table => {
		table.cols([
			{ label: 'ID', type: 'ts-number' },
			{ label: 'Name', flex: 2 },
			{ label: 'Price', type: 'ts-number'}
		]);
		table.rows(json).max(5);
	});
});
```

You can track the page with the onpage method, if for some reason you need that.

table.onpage = function(index) {
	console.log(index); // called whenever the user changes page
};

If you would like to manage paging yourself, because you have a billion products and don't want to fetch them all at once, you can create your own pager.

```
var popup = ts.ui.Notification;
ts.ui.get('#big-data-table', table => {
	table.max(10).cols([
		{ label: 'ID', type: 'ts-number' },
		{ label: 'Name', flex: 2 },
		{ label: 'Price', type: 'ts-number'}
	]);
	table.pager({
		pages: 5,
		page: 0,
		onselect: loadpage
	});
	function loadpage(index) {
		var url = 'assets/page-' + index + '.json';
		$.getJSON(url, function(json) {
			var n = json.length;
			popup.success('Loaded ' + n + ' rows');
			table.rows(json);
		});
	}
	loadpage(0);
});
```

If you need to update the index later on, for example to support history navigation, it is recommended that you change the page property of the existing Pager instead of initializing a whole new Pager. You can just call the same method without arguments.

mytable.pager().page = 23;
