read_html incorrectly parses a table from Wikipedia
#### Code Sample, a copy-pastable example if possible

```python
import pandas as pd
import html5lib
import requests
from lxml import html
from lxml import etree

url = "https://en.wikipedia.org/wiki/Comparison_of_single-board_computers"
xpath = "//*[@id=\"mw-content-text\"]/table"

res = requests.get(url)
tree = html.fromstring(res.content)
tables = tree.xpath(xpath)

# for index, t in enumerate(tables):
#     print("Table index [%s]" % index)
#     print(t.xpath('descendant-or-self::th/text()'))
#     print

headers = ['Name', 'PCIe', 
           'USB 2.0', 'USB 3.0', 'USB devices', 
           'Storage on-board', 'Storage flash slots', 'Storage SATA', 
           'Networking ETH', 'Networking WiFi', 
           'Communication bluetooth', 'Communication I2C', 'Communication SPI', 
           'Generic I/O GPIO', 'Generic I/O Analog', 
           'Other interfaces']
# at the beginning and at the end there are 2 unnecessary rows, 
# because the original header was to complex for the parser, so it's removed
dta = pd.read_html(html.tostring(tables[2]), skiprows=2)[0][:-2]
dta.columns= headers
dta.sort_values(by=['Name'])[61:]
```

#### Problem description

Roughly, starting from id=69 everything seems to be mixed. Either it's because of the parsing library or the specific of the table from Wiki. Values looks like they are shifted to the left.

#### Expected output

e.g. "Orange Pi Lite" should have USB3.0 == "No", instead there is "b/g/n (RTL8189FTV)", and that value should be shifted 5 columns to the right

#### Output of ``pd.show_versions()``
