The document is not complete. When it comes to formatting, it is also not fine work. Are tables in tables. Do not work fine if you want to take it over in your own document.

This is not right. The entire chapter is summarized and there are no tables in tables. It's always hard to copy a stuvia summary into your own document about violating copyright:)
