Webform Integration - Permission level for viewing the civicrm contact name column
The permissions per webform module overrides the webform permissions. When this module is installed and enabled, there will be a tab on the form settings called 'Permission settings' for every webform node. With this you can control the results tab on each webform by role. You can use only the Access webform results and Edit webform results.

Please test this module before using on production
