Is it possible to split one cell into new rows in excelHtml5 export?

Hi all, i'm trying to export in excel but i need to format like this:
1. I have some cells with inside table in it
1.1. I need those cells to convert in new rows in the excel (Formatting </tr> as \n\r, see image 1.

This is what i have done so far (For the record, I already make it possible to wrap text in one cell, but what i need is to create new rows instead wrapping them inside the cell):

'buttons' => [
                            [
                                'extend' => 'excelHtml5',
                                'text' => '<i class="far fa-file-excel processing" style="font-size:18px"></i>',
                                'className' => 'btn btn-outline-excel btn-sm',
                                'messageTop' => $messageTop,
                                'exportOptions' => [                                
                                    'columns' => ':visible',
                                    'format' => [
                                        'body' => 'function ( data, row, column, node ) {
                                            data = data.replace(/<br\s*[\/]?>/gi, " ");
                                            data = data.replace(/<tr\s*[\/]?>/gi, "\n");

Can anyone knows a way to achieve that?

Thanks in advance.
