# DataTables example Show / hide columns dynamically

This example shows how you can make use of the `column().visible()` API method to dynamically show and hide columns in a table. Also included here is scrolling, just to show it enabled with this API method, although that is not required for the API function to work.

In addition to this, groups of columns can be shown and hidden at the same time using the `columns()` method to select multiple columns and then using the `columns().visible()` method to set their state.

If you are looking for a more complete column visibility interaction controls, check out the Buttons extension for DataTables provides a comprehensive module for column visibility control.

- Javascript
- HTML
- CSS
- Ajax
- Server-side script

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

`$(document).ready(function() { var table = $('#example').DataTable( { "scrollY": "200px", "paging": false } ); $('a.toggle-vis').on( 'click', function (e) { e.preventDefault(); // Get the column API object var column = table.column( $(this).attr('data-column') ); // Toggle the visibility column.visible( ! column.visible() ); } ); } );`

In addition to the above code, the following Javascript library files are loaded for use in this example:

- //code.jquery.com/jquery-1.12.3.min.js
- ../../media/js/jquery.dataTables.js

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:

- ../../media/css/jquery.dataTables.css

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.
