Bufferview and scrollview cannot load data

[officecode]

In the following sample code, if the 'view' is removed, the data can be loaded and displayed normally. If you add 'view', you can see the server's return data in the console, but the datagrid display is empty.
Why is that? Where is the writing wrong? Please correct me, thank you!

Code:

$('#p').datagrid({
	url:'test.php',
	columns:[[......]],
	view:scrollview,
})

[officecode]

The datagrid must have a height attribute.
solved!
