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.

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

https://camelot-py.readthedocs.io/en/master/user/advanced.html#detect-short-lines

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

Please assist.
