Scrape tables into dataframe with BeautifulSoup

Question

I'm trying to scrape the data from the coins catalog.

There is one of the pages. I need to scrape this data into Dataframe

So far I have this code:

import bs4 as bs
import urllib.request
import pandas as pd

source = urllib.request.urlopen('http://www.gcoins.net/en/catalog/view/45518').read()
soup = bs.BeautifulSoup(source,'lxml')

table = soup.find('table', attrs={'class':'subs noBorders evenRows'})
table_rows = table.find_all('tr')

for tr in table_rows:
    td = tr.find_all('td')
    row = [tr.text for tr in td]
    print(row)                    # I need to save this data instead of printing it 

It produces following output:

[]
['', '', '1882', '', '108,000', 'UNC', '—']
[' ', '', '1883', '', '786,000', 'UNC', '~ $3.99']

['', '', '1896', '', '174,000', 'UNC', '—']

But when I'm trying to save it to Dataframe and export to excel it contains just the last value:

         0
0         
1         
2     1896
3         
4  174,000
5      UNC
6        —

Pandas already has a built-in method to convert the table on the web to a dataframe:

table = soup.find_all('table')
df = pd.read_html(str(table))[0]
