Here I set as described the data table thousand separator, but it doesn’t work the way I expected.
Can anybody help me?
$('#example').dataTable( { "language": { "thousands": "'" }} );table.dataTable thead th { border-bottom: 0;}table.dataTable tfoot th { border-top: 0;}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><link href="http://cdn.datatables.net/rowreorder/1.0.0/css/rowReorder.dataTables.css" rel="stylesheet"/><script src="https://cdn.datatables.net/1.10.9/js/jquery.dataTables.js"></script><script src="https://cdn.datatables.net/rowreorder/1.0.0/js/dataTables.rowReorder.js"></script><link href="http://cdn.datatables.net/1.10.0/css/jquery.dataTables.css" rel="stylesheet"/><script src="http://cdn.datatables.net/plug-ins/1.10.24/sorting/formatted-numbers.js"></script><table id="example"> <thead> <tr> <th>Seq.</th> <th>Name</th> <th>Position</th> <th>Office</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tbody> <tr> <td>2</td> <td>Tiger Nixon</td> <td>System Architect</td> <td>Edinburgh</td> <td>2011/04/25</td> <td>320800</td> </tr> <tr> <td>22</td> <td>Garrett Winters</td> <td>Accountant</td> <td>Tokyo</td> <td>2011/07/25</td> <td>170750</td> </tr> <tr> <td>6</td> <td>Ashton Cox</td> <td>Junior Technical Author</td> <td>San Francisco</td> <td>2009/01/12</td> <td>86000</td> </tr> <tr> <td>41</td> <td>Cedric Kelly</td> <td>Senior Javascript Developer</td> <td>Edinburgh</td> <td>2012/03/29</td> <td>433060</td> </tr> <tr> <td>55</td> <td>Airi Satou</td> <td>Accountant</td> <td>Tokyo</td> <td>2008/11/28</td> <td>162700</td> </tr> <tr> <td>21</td> <td>Brielle Williamson</td> <td>Integration Specialist</td> <td>New York</td> <td>2012/12/02</td> <td>372000</td> </tr> <tr> <td>46</td> <td>Herrod Chandler</td> <td>Sales Assistant</td> <td>San Francisco</td> <td>2012/08/06</td> <td>137500</td> </tr> </tbody> </table>Thanks

Answer
You can use a column render function to convert your source data from numbers without thousands separators to the format you want.
$(document).ready(function() { var table = $('#example').DataTable( { "lengthMenu": [ 5, 10, 50, 100 ], // just for testing! columnDefs: [ { targets: [5], render: function ( data, type, row, meta ) { return '$' + parseInt(data).toLocaleString('en-US'); } } ] } );} );<head> <meta charset="UTF-8"> <title>Demo</title> <script src="https://code.jquery.com/jquery-3.5.1.js"></script> <script src="https://cdn.datatables.net/1.10.22/js/jquery.dataTables.js"></script> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.22/css/jquery.dataTables.css"> <link rel="stylesheet" type="text/css" href="https://datatables.net/media/css/site-examples.css"></head><body><div style="margin: 20px;"> <table id="example" class="display dataTable cell-border" style="width:100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office in Country</th> <th>Age</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tbody> <tr> <td>2</td> <td>Tiger Nixon</td> <td>System Architect</td> <td>Edinburgh</td> <td>2011/04/25</td> <td>320800</td> </tr> <tr> <td>22</td> <td>Garrett Winters</td> <td>Accountant</td> <td>Tokyo</td> <td>2011/07/25</td> <td>170750</td> </tr> <tr> <td>6</td> <td>Ashton Cox</td> <td>Junior Technical Author</td> <td>San Francisco</td> <td>2009/01/12</td> <td>86000</td> </tr> <tr> <td>41</td> <td>Cedric Kelly</td> <td>Senior Javascript Developer</td> <td>Edinburgh</td> <td>2012/03/29</td> <td>433060</td> </tr> <tr> <td>55</td> <td>Airi Satou</td> <td>Accountant</td> <td>Tokyo</td> <td>2008/11/28</td> <td>162700</td> </tr> <tr> <td>21</td> <td>Brielle Williamson</td> <td>Integration Specialist</td> <td>New York</td> <td>2012/12/02</td> <td>372000</td> </tr> <tr> <td>46</td> <td>Herrod Chandler</td> <td>Sales Assistant</td> <td>San Francisco</td> <td>2012/08/06</td> <td>137500</td> </tr> </tbody> </table></div></body>This has the following features:
It will work for every record in the table, not just for those which are displayed on the first page.
It does not require a regular expression such as
data.replace(/B(?=(d{3})+(?!d))/g, ",");– and is therefore easier to understand.It uses JavaScript’s built-in support for number formatting using
toLocaleString. This means it is also possible to change the thousands separator by applying a different locale (the language tag). For example, if you replace'en-US'withfr-FR, then you will get the type of thousands separator used in France, which is a space – so$320 800instead of$320,800.
The above code assumes the source data is provided as number without a currency symbol:
<td>320800</td>If the source data already has a currency symbol at the start of the string, for example, like this:
<td>$320800</td>then you would need to adjust the render function as follows:
render: function ( data, type, row, meta ) { return data.substring(0, 1) + parseInt(data.substring(1)).toLocaleString('en-US');}
