To do so, unfortunately, you'd have to edit the module files. E.g., for 'proteins', the file modules/proteins.php'. That'd require some understanding of PHP and HTML. If it's a simple change I can help you with the code modification.
(The next release of LabStoRe will provide this feature that you are looking for.)
There is another way too. LabStoRe uses a sub-application, 'interface creator', which by itself can be used to view, edit, delete, etc., records. The sub-application pages look different but provide the same functionality. Further, as an admin you can set what fields should be shown in the lists of records, etc. To access your database through the sub-application, browse to your_website/the_LabstoRe_folder/interface_creator/index.php and explore it.
