Data Table

Hi,

I have created a data table by the following steps 

1.Create data table then i have entered the name 
2.Import file → CSV file was uploaded 
3.Configure Columns -→ primary key was set 

While i am referencing the column in Rule it is not working.
This was in the data table 

I have added the below line. It was not taking the column field .

 not ($e.target.resource.attribute.labels["res_metadata_namespace"] in %test1.namespace )
