Automatic addition of row ID attributes

Often when using server-side processing you will find that it can be useful to have a specific ID on each row (the primary key value from the database for example). By assigning the ID you want to apply to each row using the property DT_RowId of the data source object for each row (this property name can be configured using the rowId option), DataTables will automatically add it for you (note that this will work for Ajax and Javascript loaded data as well as for server-side processing).

In addition to DT_RowId there are other properties which perform similar actions - please refer to the server-side processing section of the manual for full details.

This example below shows DT_RowId being used to add information to the table. In addition objects are used as the data source for the rows.

First name	Last name	Position	Office	Start date	Salary
First name	Last name	Position	Office	Start date	Salary

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

$('#example').DataTable({
	ajax: 'scripts/ids-objects.php',
	columns: [
		{ data: 'first_name' },
		{ data: 'last_name' },
		{ data: 'position' },
		{ data: 'office' },
		{ data: 'start_date' },
		{ data: 'salary' }
	],
	processing: true,
	serverSide: true
});

new DataTable('#example', {
	ajax: 'scripts/ids-objects.php',
	columns: [
		{ data: 'first_name' },
		{ data: 'last_name' },
		{ data: 'position' },
		{ data: 'office' },
		{ data: 'start_date' },
		{ data: 'salary' }
	],
	processing: true,
	serverSide: true
});

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.
