Distinguishing between Layers and TableView using ArcPy?

I am working with ArcMap and am using ArcPy.

My task is to loop through mxds and find broken data sources.

My code is:

mxd = arcpy.mapping.MapDocument(fullPath)
brknMXD = arcpy.mapping.ListBrokenDataSources(mxd)
for brknItem in brknMXD:  
    if brknItem.supports("workspacePath"):
        try:
            source = brknItem.workspacePath
            print  str(brknItem) + ": " +  source
        except:
            print "unexpected error"
            continue
    else:
        print "Layer does not support source"

Some mxds have TableViews and that is where the code breaks.

Traceback (most recent call last): File
“P:ScriptsFind_MXDs_Broken_Sources.py”, line 5, in
if brknItem.supports(“workspacePath”): AttributeError: ‘TableView’ object has no attribute ‘supports’

I checked within an mxd python interpreter to see what type of objects are return by arcpy.mapping.ListBrokenDataSources(mxd) and it indicated:

>>> for each in brknMXD:
...     print type(each)
...     
<class 'arcpy._mapping.Layer'>
<class 'arcpy._mapping.Layer'>
<class 'arcpy._mapping.Layer'>
<class 'arcpy._mapping.TableView'>

Clearly I can just set a test to distinguish between these two types, but I don’t know how exactly to write it.

Any ideas?
