This paper introduces iTBLS, an interactive tabular dataset based on data from ArXiv, a pre-release academic paper website. iTBLS consists of three types of tabular tasks: interpretation, modification, and generation. Interpretation focuses on understanding tables, modification focuses on manipulating table information, and generation focuses on adding new natural language evidence. Furthermore, we present a novel framework for reconstructing tabular tasks as question-answering. This framework formulates appropriate questions based on the characteristics of user interactions and uses user requests as evidence to answer them. This approach improves performance across all tasks in iTBLS compared to sequence-to-sequence modeling baselines. Furthermore, the proposed question-answering-based reconstruction method is applied to an existing text-to-table task dataset that summarizes text into tables, improving accuracy (Exact-Match) by up to 13% and BERTScore by up to 16% compared to the state-of-the-art.
