# DataTables example Multi-column ordering

DataTables allows ordering by multiple columns at the same time, which can be activated in a number of different ways:

- User shift click on a column (added the clicked column as a secondary, tertiary etc ordering column).
- On a per-column basis (i.e. order by a specific column and then a secondary column if the data in the first column is identical), through the `columns.orderData` option.
- Using the `columns.orderData` option to specify a multiple column order by default (for example `[ 0, 1 ]`).
- Through the `order()` API method.

Note that, the ability for the user to shift click to order multiple columns can be disabled through the `orderMulti` option.

The example below shows the first column having a secondary order applied to the second column in the table, vice-versa for the second column being tied directly to the first and the salary column to the first name column.

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

`$('#example').DataTable({ columnDefs: [ { targets: [0], orderData: [0, 1] }, { targets: [1], orderData: [1, 0] }, { targets: [4], orderData: [4, 0] } ] });`
`new DataTable('#example', { columnDefs: [ { targets: [0], orderData: [0, 1] }, { targets: [1], orderData: [1, 0] }, { targets: [4], orderData: [4, 0] } ] });`

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.
