Hi Tali

The structure of Data Lens Layout is unique to each file. 

If you want to make this a permanent layout, you can navigate to Setup...Project Preferences...General. Then select Change Startup Defaults:

It will open a new window. Select User Selected System.
Then under Initial Lens File, select a file with the right layout.

It should each time open a new file with that layout.
I haven't tested this, so please let us know how it goes.

Thank you!

Hi Tali

To set-up correctly the column width, there is a reset button:
