jQuery DataTables

We can use the JavaScript library DataTables to generate enhanced tables in HTML. In the example below, we create a table for the mtcars data:

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.

<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:

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:

kable(head(mtcars), 'html')
