Lookupvalue but column doesnt exist

Hi, I am trying to set up a table where not all the columns are present in the source table.

 

example

 

Col 1, Col 2, Col3,Col4

 

Source data only has Col1 and 3

 

So I want populate Col and 3 with the data and leave the other blank

 

I have tried in M Query and it takes over 30mins to load 50 columns

 

I have also tried in Dax lookupvalue , but as the column doesnt exist in the source file it errors.

Is there a way to subdue this error

 or is there a better way to do this 

Thank you

@Julian_H I'm not quite understanding this scenario. Can you maybe elaborate along with some sample data?

Apologies, 

 

I have a template table with all the columns I need in,but the source file only has a few of these columns.

How do I populate the template with columns that are available in the source file and leave all the other blank
