TypeError: bad operand type for unary ~: 'float'

[PL450]

Hi,
For pdf pages with similar layout to the Sample_FS.pdf, I get the above error. I think the code should work fine for similar layouts. So what is the issue? Can I solve the issue by some simple tweaking of the code?

Thank you

Hi

The above error occurred even when the page has only 1 table and the headers of the table are in year. There is a title above the table, similar to the Sample_FS.pdf.

The page is pg 92 in the attached pdf dbs_2020.pdf.
