Here is our solution to this:

using OfficeOpenXml;

public class XmlService
{
    // [...]
    public void getXlsxFile(SomeTableObject tbl, ref byte[] bytes)
    {
        using (ExcelPackage pck = new ExcelPackage())
        {
            ExcelWorksheet ws = pck.Workbook.Worksheets.Add(tbl.name);
            ws.Cells["A1"].LoadFromDataTable(tbl, true);
            bytes = pck.GetAsByteArray();
        }
    }
}
