How to download or place a copy of original tables with locked-permissions via remote connection in Oracle SQL Developer?
Evidently, this is how you copy tables from databases with permissions via remote connection to a local file-folder on Oracle SQL Developer (Mac OS X Yosemite):


Target database and expand to view tables.
Select desired table and right-click.
Hover-over 'Table' and select 'Copy'
A pop-up window will prompt to save copy table-name.


I've attached a screenshot below for clarification.  Thanks!
