Hello,
If you mean show more columns in the view, you can add more columns using the columns menu and selecting which columns you would like to see. The following animation shows how to show/hide columns

If you mean to include more columns apart from the default ones, you can create custom metadata. Then, every property you create will appear in the columns menu to be shown or hidden. You can check
this video at 1:50 to see how to create custom properties.
Let me know if it's clear or if I haven't understood your question.
Regards,
