Abount the detail of the dataset.

I find there are several fields of each sample in the dataset, which are dict_keys(['question_id', 'original_table_id', 'question', 'sql', 'answer', 'hard_positive_idx', 'positive_idx', 'negative_idx', 'dataset']).

1. Could you provide a comment about the meaning of each field?
2. Literally, positive idx means the index of relevant tables, however, I find some positive_idx are empty lists ([]), does it mean there are no relevant tables for this question？ and how do you feed empty tables into the encoder?
