arcpy - Python Script Zonal Stats as Table Loop Question

I'm trying to write a small script loop script which retrieves rasters from each folder, performs zonal statistics using watershed polygons and saves it as a table. I've written similar loop scripts, but this seems to be confusing me. Here's what I have so far:

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "F:/lu_crop_rast"
arcpy.env.overwriteoutput = 1

watershedFeat = "F:/watersheds.shp"
outDir = "F:/lu_crop_rast/tables/"


for raster in arcpy.ListRasters():
    outTable = outDir + raster + "_TBL.dbf"
    arcpy.sa.ZonalStatisticsAsTable(watershedFeat,"Name",raster,outTable,"NODATA","MEAN")

This is the error I'm getting:

Runtime error  Traceback (most recent call last):   
File "", line 15, in    File "c:\program files (x86)\arcgis\desktop10.3\arcpy\arcpy\sa\Functions.py", line 6232, in ZonalStatisticsAsTable     statistics_type)

I've checked and my rasters and shapefile aren't corrupt. I've looked at this thread as well and made the following changes:

arcpy.gp.ZonalStatisticsAsTable_sa(watershedFeat,"Name",raster,outTable,"NODATA","MEAN")

But so far nothing seems to work.

Answer

You need to dedent and modify your naming (thanks Tom). Try this:

import arcpy, os
arcpy.env.overwriteOutput = True

-

for raster in arcpy.ListRasters():
    raster_name = os.path.basename(raster).rstrip(os.path.splitext(raster)[1])
    outTable = outDir + raster_name + "_TBL.dbf"
    arcpy.gp.ZonalStatisticsAsTable(watershedFeat,"Name",raster,outTable,"NODATA","MEAN")
