How I can cancel download file csv

How I can cancel download

onDownload: (buildHead, buildBody, columns, data) => {
        // cancel here
      },

How can I cancel the file download, to use another file format

I think you're looking for these options

which allow you to change the file name. I'm not sure cancelling the download is what you want, as that will stop it from occurring entirely.

return false

Hello team, this is a portion of my code (which is weird but works with excel...)

    handleOnDownload(buildHead, buildBody, columns, data)  {
        let csvContent = buildHead(columns) + buildBody(data);
        var a = document.createElement('a');
        var textFileAsBlob = new Blob(["\ufeff",csvContent], {
            type: 'text/csv;charset=UTF-8',
            encoding: "UTF-8"
          });
        a.href = window.URL.createObjectURL(textFileAsBlob);
        a.download = 'exportCims.csv';
        a.click();
        return false;
    }

my option on my grid is

downloadOptions: {filterOptions : {useDisplayedRowsOnly : true}},
onDownload: (buildHead, buildBody, columns, data) => {this.handleOnDownload(buildHead, buildBody, columns, data)},

the return false does not work... ? (mui-datatable 3.7.3)

Same problem with return false here:

	_onDownload = () => {
		console.log('_onDownload');
		return false;
	}

The file is still downloaded. Version 3.7.6

I can confirm this is still an issue. (mui-datatables 3.7.7)
