Construct a reactive expression that reads Tableau data schema

Creates a reactive expression that returns schema data for the specified Tableau data table, including the names and data types of columns. Basically, this is a convenience wrapper that takes a spec object in any of its various forms, invokes either tableau_worksheet_info() or tableau_datasource_info() as appropriate, and extracts the specific sub-object that matches spec.

reactive_tableau_schema(spec, session = shiny::getDefaultReactiveDomain())

Arguments

spec	See reactive_tableau_data().
session	The Shiny session object. (You should probably just use the default.)

Value

A named list, as described in the DataTableSchema topic.
