所以我做了一个小项目，使用camelot从pdf文件中读取表格（pip install camelot） 我得到了我需要的输出，但它全部排成一行，所以我想知道是否可以从此代码在 json 文件中插入一个新行
import camelot
file = "file.pdf"
tables = camelot.read_pdf(file, pages='2-end', line_scale=40)
tables.export('files.json', f='json', compress=True) # works for csv, tsv, xsml

这是我的输出，但我需要更引人注目的输出
