I have created a lightning:datatable to display order lines. The order lines are fetched via a REST call. I parse the JSON response and add to the datatable data attribute. Everything works fine but how the values is displayed. I guess it is the same issue as with Salesforce Standard UI, but one might thing you have some more possibilities when you are writing custom code?

TL;DR
How do I remove the spacing for number columns in my lightning:datatable?
