[delonleo]

Thank you for the meaningful work here.

Could you please provide sample files for doc.csv and doc_select.csv with 1 line of placeholder data in each column? This will greatly assist us in comprehending the training data format. Much appreciated.

I found you also used a lot of public datasets, such as ICDAR series competitions, so could you give some detailed data formats of these data. This also can help us in comprehending the training data format.
