By default, AutoFill will increment cells that contain numbers by a single digit for each cell that
is iterated over (try the Age column below for example). This behaviour can be disabled
completely using the increment column option, but it can also be modified to suit your
requirements through use of the step column callback function.
The step callback is executed for each cell in the auto-fill set and gives complete
control over how data is incremented. The example below shows the step function being used on the
Salary column to increment by 100, rather than 1 for each cell.
For a complete description of the step callback, please refer to the AutoFill documentation.

The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
var table = $('#example').dataTable();
new $.fn.dataTable.AutoFill( table, {
columnDefs: [ {
targets: -1,
step: function ( cell, read, last, i, x, y ) {
var val = parseInt( (last || read).replace(/[$,]/g, ''), 10 );
val += (x<0 || y<0 ? -100 : 100); // - if going back up, + if going down
// Format for the currency column
return '$'+val.toString().replace( /\B(?=(\d{3})+(?!\d))/g, ',' );
}
} ]
} );
} );
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.
