It doesn't work that way <div id="datatable-with-export" data-datatable='{ "pageLength": 15, "ordering": false, "scrollY": "470px", "pagingOptions": { "pageBtnClasses": "btn btn-text btn-circle btn-sm" }, "layout": { "top2": "searchPanes", "top1": { "buttons": [ { "extend": "copy", "className": "btn btn-primary btn-outline btn-sm", "text": "Копировать" }, { "extend": "csv", "className": "btn btn-primary btn-outline btn-sm", "text": "CSV" }, { "extend": "excel", "className": "btn btn-primary btn-outline btn-sm", "text": "Excel" } ] } }, "searchPanes": { "controls": true, "layout": "columns-2", "cascadePanes": true, "initCollapsed": true, "i18n": { "collapseMessage": "Скрыть фильтры", "showMessage": "Показать фильтры", "clearMessage": "Сбросить фильтры", "title": "Активные фильтры - %d" } }, "columnDefs": [ { "searchPanes": { "show": true }, "targets": [0] }, { "searchPanes": { "show": true }, "targets": [1] }, { "searchPanes": { "show": false }, "targets": [2] }, { "searchPanes": { "show": false }, "targets": [3] }, { "searchPanes": { "show": false }, "targets": [4] } ] }' <script> window.addEventListener('load', () => { const dataTable = new HSDataTable('#datatable-with-export', { columnDefs: [ { targets: [-1], render: function(data, type, row) { var cleanedData = data.replace(',', '.'); var num = parseFloat(cleanedData).toFixed(2); return isNaN(num) ?

I would say its nearly impossible to debug the non-working code without seeing the problem replicated. Your code has a lot going on and it will take someone else a lot of time to come up to speed to understand your solution. One way to get development help with your solution is to use one of the Datatables support packages. Kevin
