Instead of cart use ToDrive for exporting as CSV
Export.table.toDrive({ collection: table1, description: 'this file is time series', fileNamePrefix: 'this is discription', fileFormat: 'CSV' });
Export.table.toDrive({
collection: table1,
description: 'this file is time series',
fileNamePrefix: 'this is discription',
fileFormat: 'CSV'
});
