This is for issue #375, for West Virginia.
It was a large pdf on their workforce site pdfplumber extracted the tables pretty well, although there were some irregularities in the pdf (for example, some tables had boxes that had the specific sites of the layoffs).
There are a couple of errors on their end (switching up values), but nothing too significant.

@Ash1R. I am still seeing MI being deleted from the repo, I think. Do you see this same thing on the files tab?

Why is it necessary to the range in the loop here? Can you not simple do something more like for row in data?

[Ash1R]

Each company's data is contained in two consecutive rows, with some blank rows in between these company row-pairs. Alternative company names and addresses are stored on the second row. I used range so I can access the second row using an index of k + 1. I did unnecessarily use range later, so I removed that.

mypy is flagging some type errors:
warn/scrapers/wv.py:65: error: Item "None" of "Optional[str]" has no attribute "strip" [union-attr]
warn/scrapers/wv.py:66: error: Item "None" of "Optional[str]" has no attribute "strip" [union-attr]
warn/scrapers/wv.py:68: error: Item "None" of "Optional[str]" has no attribute "strip" [union-attr]

warn/scrapers/la.py:170: note: By default the bodies of untyped functions are not checked, consider using --check-untyped-defs [annotation-unchecked]

@Ash1R , I think I see maybe an easy way to work around the mypy type conflict and also maybe make this a bit more readable, something like:

if not data[k][0]:
     rowkey = None
else:
    rowkey = data[k][0].strip()

Then start folding in those changes into the flagged rows, like if rowkey in in header_whitelist: and then keep working down to down. Last bit might be more readable as elif ((not rowkey) and (k != 0)) ... ?

The landing page perhaps has been killed off. This is the closest I could find, and I can't guarantee it'd be updated in the same way notice after notice. https://workforcewv.org/about-us/

I have not tried seeing if this scraper works with that PDF.
