Vue tables followup work. (#2162)

- Allow 'editable' property on view providers to optionally be a function
 - CSVExporter now only exports visible columns. Updated CSVExporter to ES6 exports / imports
 - Shortcut sortedIndex in insert if value is outside of first or last value in collection
 - Added table view icon
