merged cells not working as expected

I followed this example (same code, same image/pdf):
https://aws.amazon.com/blogs/machine-learning/merge-cells-and-column-headers-in-amazon-textract-tables/


`print (df)` shows:
```
Date Description Details Credits Debits Balance
0 2/4/2022 Life Insurance Payments Credit 445 9500.45
1 2/4/2022 Property Management Credit 300 9945.45
2 2/4/2022 Retail Store 4 Credit 65.75 10245.45
3 2/3/2022 Electricity Bill Credit 245.45 10311.2
4 2/3/2022 Water Bill Credit 312.85 10556.65
5 2/3/2022 Rental Deposit Credit 3000 10869.5
6 2/2/2022 Retail Store 3 Credit 125 7869.5
7 2/2/2022 Retail Store 2 Refund Debit 5.5 7994.5
8 2/2/2022 Retail Store 1 Credit 45.5 8000
9 2/1/2022 Shoe Store Refund Credit 33 8045.5
10 2/1/2022 Snack Vending Machine Debit 4 8012.5
```
Note the lack of "Amount".
Can anyone shed some light on this?

首先，使用报告中的图像或 PDF 运行链接的 AWS Textract 合并单元格示例，并将其 dataframe 输出与预期的 Amount 列进行比较。然后跟踪该示例所使用的 repository 示例，以确定合并单元格的值在哪里处理。复现问题并在不更改其他提取列的情况下恢复缺失的 Amount 字段，即表示完成。
