Standalone tables are erroneously included when publishing a single layer in an ArcGIS Pro map through ArcPy.

Workaround

Remove the table and save before publishing:

search_table = mp.listTables()[0]

print("Table is ",search_table)

mp.removeTable(search_table) #REMOVE TABLE FROM PRO

print("Table is ",search_table)

prj.save()

for mp in maps:

publish_layer = mp.listLayers()[0]

arcpy.mp.CreateWebLayerSDDraft(publish_layer, sddraft, "Habitatz", 'MY_HOSTED_SERVICES', 'FEATURE_ACCESS','', True, True, False, True, False)#create sddraft

arcpy.StageService_server(sddraft, sd)

arcpy.UploadServiceDefinition_server(sd, 'My Hosted Services')

print("UPDATING LAYER")

Add the table back when needed.
