# jQuery DataTables

We can use the JavaScript library [**DataTables**](http://www.datatables.net) to generate enhanced tables in HTML. In the example below, we create a table for the `mtcars` data:

```{r cool, results='asis'}
library(knitr)
kable(mtcars, 'html', table.attr='id="mtcars_table"')
```

Note we assigned an `id` to the table, and next we use the **DataTables** library to tweak the table.

```js
<script type="text/javascript">
	$(document).ready(function() {
		$('#mtcars_table').DataTable();
	} );
</script>
```



Since this is a Markdown vignette, we need to add the JavaScript libraries as well as some additional CSS files to the HTML header, and this can be done via:

```{r}
options(markdown.HTML.header = system.file('misc', 'datatables.html', package = 'knitr'))
```

The file `datatables.html` under the `misc` directory of **knitr** was added to the HTML output.

By comparison, below is an ordinary table:

```{r boring, results='asis'}
kable(head(mtcars), 'html')
```

This vignette is only a toy example. I'd recommend you to use the **DT** package instead: https://github.com/rstudio/DT
