• Abstract: Large Language Models (LLMs) often struggle with data-analytics requests related to information retrieval and data manipulation that frequently arise in real-world scenarios under multiple conditions. In this paper, we introduce Thinking with Tables, where we inject tabular structures into LLMs for data-analytics requests. Through comprehensive evaluations across various request types, we show that providing tabular structures yields a 40.29 percent average performance gain along with better robustness and token efficiency. Through attention-value analysis, we uncover that tables help LLMs better attend to relevant information, explaining these improvements. Beyond tables and text, we evaluate whether (1) blending structuredness within text, such as providing templates or fixing the order of attributes, and (2) other representative structures, such as knowledge graphs and JSON, are helpful. We observe that utilizing tables offers the best balance between efficiency and effectiveness. These advantages remain consistent under increased task complexity and even when all input data cannot be structured. Finally, as data analytics typically relies on structured factual inputs, our text-to-table conversion demonstrates the method's applicability to text-compatible data sources.

• Table Retrieval May Not Necessitate Table-specific Model Design [83.27735758203089]
  We focus on the task of table retrieval, and ask: "is table-specific model design necessary for table retrieval?" Based on an analysis on a table-based portion of the Natural Questions dataset (NQ-table), we find that structure plays a negligible role in more than 70% of the cases. We then experiment with three modules to explicitly encode table structures, namely auxiliary row/column embeddings, hard attention masks, and soft relation-based attention biases. None of these yielded significant improvements, suggesting that table-specific model design may not be necessary for table retrieval.
