Spike: Missing copy item barcode icon (May need to adjust column widths)

1. Go to Inventory
2. Search by l
3. Click on first title for L’Apprenti sorcier / Paul Dukas

Expected: A copy icon should appear to the right of each item's barcode

Actual: No copy icon displays to the right of each item's barcode

I think if we remove the columnWidths property in src/Items.js, we'll see the columns auto-size their width based on the data the contain and get the formatting we want here, more or less:

• columns shrink to be as narrow as possible without cutting off any values
• column values do not wrap; all are displayed on one line
• horizontal scroll bars appear as necessary
