Update perspective-viewer after server table clear

[mbcastledine]

I have set a server table on a perspective-viewer instance, a clear() on the server side does not result in the client side clearing the data.

Is this expected behaviour? If so, is there any way for me to get the result I am after (clearing the client side) table?

Think you should just be able to .remove all the keys?

clear() is not implemented for client/server replicated mode yet. If you're using PerspectiveWidget in Jupyter, using server-only mode with server = True kwarg is a workaround, or if this is an app, you can pass your WebSocket Table instance directly to the viewer's load() method.

There are a few open issues for this already from different contexts.
