In the export Button :

```python
# 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.
