two single row tables in two separate pdfs don't bet read by camelot as tables

Windows-10-10.0.19043-SP0
Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)]

**Describe the bug**
2 of 55 pdfs with K-12 education table data have one row tables that don't process as tables.
https://www.dpi.nc.gov/media/8350/open
https://www.dpi.nc.gov/media/8325/open

It doesn't find a table, likely related to one row entry.

**Steps to reproduce the bug**
ran:
tables = camelot.read_pdf(weburl, pages='all')
where weburl is set to the above two urls in a loop.

**Expected behavior**

Should have one row table output for these two separate 1 page pdfs.

**Code**

tables = camelot.read_pdf(weburl, pages='all')

```
import camelot

# add your code here

```

**Additional context**

there are 55 educator prep urls being cycled through in a loop.
These two failed to produce tables, and I bet it's related to only have one row entry after headers or something.

Reproduce the issue with camelot.read_pdf(weburl, pages='all') using the two linked North Carolina PDF URLs and the reported Python, NumPy, OpenCV, and Camelot versions. Compare these one-page, single-row documents with the other 53 educator-preparation PDFs to identify why no table is returned. Done means both PDFs produce the expected one-row table output.
