Thanks @Hkesharwani for your replying,
As DLT doesn't support the magic command %run, that's why I'm trying the import function way
my layout like this:
other notebook:
import os
import sys
sys.path.append(os.path.abspath('/Workspace/Repos/[my repo]/dw/common_helper'))
from udf_check_table_exists import table_exists
But it always returns ModuleNotFoundError error
