Thousands separator is not applied - datatables

Question

I use jQuery DataTable :
$(document).ready(function() {
var table = $('#t_list').DataTable({
"language": {
"decimal": ",",
"thousands": " ",
"emptyTable": _getText("datatable.resultat.zero"),
"info": _getText("datatable.zone.statut.info"),
"infoEmpty": "",
"infoFiltered": _getText("datatable.zone.statut.filtre"),
"lengthMenu": _getText("datatable.zone.nb.affichage"),
"loadingRecords": _getText("datatable.resultat.chargement"),
"processing": _getText("datatable.resultat.processing"),
"search": _getText("datatable.zone.filtre"),
"zeroRecords": _getText("datatable.resultat.zero"),
"paginate": {
"first": _getText("datatable.btn.premier"),
"previous": _getText("datatable.btn.prcdt"),
"next": _getText("datatable.btn.svt"),
"last": _getText("datatable.btn.dern")
}
},
"pagingType": "full_numbers",
"serverSide": true,
"ajax": "<c:url value='/ajaxDataTableListUsers' />",
"columns": [{
"data": "username"
}, {
"data": "email"
}, {
"data": "salary"
}, {
"data": "id"
}],
"columnDefs": [{
"targets": 2,
"className": "alignDroite"
}, {
"targets": 3,
"render": function(data, type, row, meta) {
var client_noms = row.username; < c: url
var = "url_edit"
value = "/edit" / >
var url_edit = "${url_edit}?id=" + data;
return '<div style="text-align:center;"><img src="resources/images/edit.png" /> ' +
'<img src="resources/images/cross.png" /></div>';
}
}]
});
});
As you can see there is the thousands parameter in the language option. But at runtime the formatting is not applied :
So why is the formatting not applied ?
-- EDIT --
Source of the data is here :
#Override
#Transactional
public List<User> list(int start, int length, String search, int triIdx, String ordreTri) {
Criteria criteres = sessionFactory.getCurrentSession().createCriteria(User.class);
if (!search.equals("")) {
if (NumberUtils.isNumber(search))
criteres.add(Restrictions.like("salary", Double.parseDouble(search)));
else
criteres.add(Restrictions.like("username", search, MatchMode.ANYWHERE));
}
criteres.setFirstResult(start);
criteres.setMaxResults(length);
if (ordreTri.equals("asc")) {
switch (triIdx) {
case 0:
criteres.addOrder(Order.asc("username"));
break;
case 1:
criteres.addOrder(Order.asc("email"));
break;
case 2:
criteres.addOrder(Order.asc("salary"));
break;
default:
criteres.addOrder(Order.asc("username"));
break;
}
} else {
switch (triIdx) {
case 0:
criteres.addOrder(Order.desc("username"));
break;
case 1:
criteres.addOrder(Order.desc("email"));
break;
case 2:
criteres.addOrder(Order.desc("salary"));
break;
default:
criteres.addOrder(Order.desc("username"));
break;
}
}
criteres.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
#SuppressWarnings("unchecked")
List<User> listUser = (List<User>) criteres.list();
return listUser;
}

You don't show the source of your data.
The documenation of Datatables (https://datatables.net/manual/i18n) says that the thousands and decimal options are used when parsing your data, so that sorting can happen correctly. It doesn't look like Datatables is designed to format your data, just parse it. You should format your data as you wish it to be displayed.
