Perspective Table Export to csv?

Add a Table :

Bind Data:

In the export Button :

#   直接导出excel
 	component= self.getSibling("Table")
	dataset= component.props.data
	csv = system.dataset.toCSV(dataset)
	system.perspective.download("myExport.csv",csv)

But when I open the download file, it show ArrayWrapper?

The value of your table's data property appears to be an array of objects, not a dataset as required by system.dataset.toCSV.

So I have to use Dataset to binding in Table,not use Array.
