What you can also do is start from an already fine-tuned checkpoint. A note here is that the already fine-tuned checkpoint on WTQ has some issues due to the L2-loss which is somewhat brittle. See here for more info.

STEP 2: Prepare your data in the SQA format
Second, no matter what you picked above, you should prepare your dataset in the SQA format. This format is a TSV/CSV file with the following columns:
id: optional, id of the table-question pair, for bookkeeping purposes.
annotator: optional, id of the person who annotated the table-question pair, for bookkeeping purposes.
position: integer indicating if the question is the first, second, third,... related to the table. Only required in case of conversational setup (SQA). You don't need this column in case you're going for WTQ/WikiSQL-supervised.
