I couldn't find a way to make the +/- sign invisible based on security/user group, but I have a workaround. You can first create a new security group, and then create a dashboard extender business rule as follows:
Select Case args.FunctionType
Case Is = DashboardExtenderFunctionType.SqlTableEditorSaveData
Dim selectionChangedTaskResult As New XFSelectionChangedTaskResult()
Dim secGroup As String = "ABC" '<--Enter name Of the security Group To test for current user
Dim isUserInGroup As Boolean = BRApi.Security.Authorization.IsUserInGroup(si, secGroup)
If Not isUserInGroup
Throw New System.Exception("You are not authorized to save changes. Please contact system administrator for assistance.")
End If
End Select
This will prevent unauthorized user from saving the data.

End If
