Sharepoint 0365 List - Column Length Setting

Highlighted
Occasional Visitor

I have a sharepoint list with various views linked to it.  One of the columns has large amounts of text added with a multiple line setting.  I have found a JSON to justify this so that all the text can be seen in the views.  This has been set against this column.    See attached

Other columns were too wide for the data in them in the views so I located another JSON which seems to allow me to narrow them when set against these columns.  

I ws then using the drag feature to set the length of each column.

However my question is how can I then 'fix' these views so that the columns dont change, for example I set my column with the text so I can see it but when I change views this becomes a very narrow column. 

I am totally new to JSONs and n
