Headers are not getting extracted from PDF while extracting the table data from PDF using camelot

I am using camelot for table data extraction, however header are not getting extracted as part of the PDF.

Attaching the target PDF link below and target table are at page number 3 and 4, which need to extracted.


I have seen the the camelot documentation and I think the problem is related to the "Detect short lines"


However not able to resolve the problem by tweaking the line_size_scaling parameter.

Please assist.
