Add support for Table filter in Python Toolbox parameters

[JohnDye]

This doesn't work.

param0 = arcpy.Parameter(
    displayName="Table",
    name="in_Table",
    datatype="GPTableView",
    parameterType="Required",
    direction="Input")
param0.filter.list = ["Table"]‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It should. Please fix it.

I would love to be able to filter by the type of table, which is apparently possible, but I can't figure out how to do it.

My current workaround is to use updateMessages to check for XLSX in the catalogpath and then throw an error if it's not there.

This works, but if I want to use the nice fancy dropdown for the tableview parameter, I have to wade through every table and feature class in the map.

Please let us filter tables.
