Zusammenfassung
Returns a Python list of TableView objects that exist within a map document (.mxd).
Auswertung
ListTableViews always returns a list object even if only one table is returned. In order to return a TableView object, an index value must be used on the list (e.g., aTable = arcpy.mapping.ListTableViews(mxd)[0]). For loops on a list provide an easy mechanism to iterate through each item in the list (e.g., for aTable in arcpy.mapping.ListTableViews(mxd):).
Wildcards are used on the name property and are not case sensitive. A wildcard string of "so*" will return a layer with a name Soils. Wildcards can be skipped in the scripting syntax simply by passing an empty string (""), an asterisk (*), or entering wildcard=None, or nothing at all if it is the last optional parameter in the syntax.
It is possible that there might be tables in a map document that have the same name. If that is the case, then other properties may need to be used to isolate a specific layer. Properties such as a tables's datasource or definitionQuery could be used to do this. It is ideal that all tables in a map document be uniquely named.

Codebeispiel
ListTableViews example
The following script finds a table called TrafficAccidents in a data frame named Transportation and sets a definition query.
import arcpy
mxd = arcpy.mapping.MapDocument(r"c:\project\project.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "Transportation")[0]
table = arcpy.mapping.ListTableViews(mxd, "TrafficAccidents", df)[0]
table.definitionQuery = "[Accidents] > 5"
mxd.save()
del mxd
