Okay one of the biggest lessons I learned with working with pyqt5 is defining your own class is almost essential when trying to implement things other than just the generic operation of a particular object. Which of course is what you are attempting to do. That being said here is a more pythonic version of what you presented with the bits necessary to implement row widget contained object highlighting now you would also have to (unless you let the checkbox fill its container) set the background for the container housing the checkbox since you have limited it size to less than its container. However, if you just remove that limit it will appear as you would like it to without that extra effort but then again not sure why you limited it size so I left it as is.
Secondary note the QTableWidget is its own object and a container for your other objects (QLineEdit, QTextEdit, QComboBox) as such setting values to the QTableWidget does not affect the objects it contains to change those you have to address them directly and/or build some other feature to handle it more generically -- a QTreeView * QItemStandardModel implementation comes to mind for that -- however again did not know why you chose the QTableWidget so just made it work with that.
Oh final note -- This is Python 3.7 with pyqt5 not sure if that will be an issue for you or not
