The regular Grid report is not editable anymore. So, you cannot apply your own styles on it.
BUT I suggest you take a look at this App http://apps.jotform.com/app/submission_view also. Perhaps you can try the app to have a customize submission viewer as your report.
You can also integrate the form to Google docs spreadsheet .
In google docs application, you can create reports using data from the form submissions.
Hope this help. Inform us if there is more we can help you with.
