Thanks, I see what is the limitation and what can be done.

Just in case anyone would need I am leaving some simple JS code to export full Data Table from front-end:

<button onclick="exportToExcel('your_html_element_id', 'desired_export_file_name_and_sheet_name')">Export to Excel</button>


<script src="https://unpkg.com/xlsx/dist/xlsx.full.min.js"></script>

function exportToExcel(tableElementId,fileName) {
        // Get table element
        var table = document.getElementById(tableElementId);

        // Create a new workbook
        var wb = XLSX.utils.book_new();

        // Convert table to worksheet
        var ws = XLSX.utils.table_to_sheet(table);

        //Add all records skipping one header
        XLSX.utils.sheet_add_aoa(ws, XLSX.utils.sheet_to_json(ws, { header: 1 }).slice(1));


        // Add the worksheet to the workbook
        XLSX.utils.book_append_sheet(wb, ws, fileName);

        // Generate the Excel file and download it
        XLSX.writeFile(wb, fileName + ".xlsx");
    }

Thank you for your help. It works as described.
