# DataTables example Scrolling and Bootstrap tabs

This example shows how DataTables with scrolling can be used together with Bootstrap tabs (or indeed any other method whereby the table is in a hidden, `display:none`, element when it is initialised).

As of DataTables 2.2 when used with a browser from 2020 or newer, there is no special consideration required for this use case. However, if you need to support legacy browsers, you will notice that if the DataTable is initialised in a hidden element the browser doesn't have any measurements with which to give the DataTable, and this will result in the misalignment of columns when scrolling is enabled.

This misalignment can be corrected by the `columns.adjust()` method when the table is made visible (i.e. it has dimensions). As noted, this is not something you need to do as of DataTables 2.2, unless you need to support legacy browsers.

- JavaScript
- HTML
- CSS
- Ajax
- Server-side script

The JavaScript shown below is used to initialise the table shown in this example:

`$('table.table').DataTable({ ajax: '../ajax/data/arrays.txt', paging: false, scrollCollapse: true, scrollY: 200 }); // Apply a search to the second table for the demo $('#myTable2').DataTable().search('New York').draw();`
`new DataTable('table.table', { ajax: '../ajax/data/arrays.txt', paging: false, scrollCollapse: true, scrollY: 200 }); // Apply a search to the second table for the demo new DataTable.Api('#myTable2').search('New York').draw();`

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:

This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:

``

The following CSS library files are loaded for use in this example to provide the styling of the table:

This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.

The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
