The Excel export button saves to an XLSX file and the data can be customised before exporting the file using the customize method of the excelHtml5 button type.
This example demonstrates how to manipulate the file using this method to add a styling attribute to a row in the XML used to create the XSLX file. The object
passed into the customize method contains the XSLX's file structure and the worksheet can be accessed as shown. A jQuery selector is then used to
select the cells in row 10 and a border added. More complex logic (such as conditionally adding borders based on cell content) could of course be used.
The style added (index 25 in this case) is defined by the default styles included by Buttons. The full list of styles available and further
information about the customize method are detailed in the excelHtml5 documentation.

The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
$('#example').DataTable( {
dom: 'Bfrtip',
buttons: [ {
extend: 'excelHtml5',
customize: function ( xlsx ){
var sheet = xlsx.xl.worksheets['sheet1.xml'];
// jQuery selector to add a border
$('row c[r*="10"]', sheet).attr( 's', '25' );
}
} ]
} );
} );
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.
