Quotes
"Our classifier-free solution adopts an implicit strategy using block coverage to complete the tables."
"To address the aforementioned issues at a fundamental level, instead of explicitly labeling all the elements, we formulate a fresh perspective to implicitly fill the tables using a block-covered approach."
