问题 Note: I am a complete beginner. I am using a pandas dataframe to import a csv file that I converted from the following table. I need to load the csv file into a QTreeView and have been unable to do so.

问题 I am new to javascript and Node.js but I am trying to figure out if there is an alternative to document.getElementById() in Node that has the same function.
