我无法运行这段代码,我应该做一些事情。首先,一个数据表,我设法建立并开始工作。然后我创建了几个按钮,以便可以过滤数据表这些按钮对更改数据表没有任何作用,我需要让它们工作。其次,我正在尝试使用饼图,并使其与数据表交互饼图不呈现。最后,我还需要一个与数据表交互的地理位置图。数据表有横向位置和纵向位置地理定位也不渲染*

app
在

中,添加[Input('filter-type', 'value')])
另外,在
update_map
之前的回调中,删除Input('datatable-id',"derived_viewport_selected_rows")])
。试试看:@app.callback(Output('map-id', "children"), [Input('datatable-id', "derived_viewport_data")])
