extractor.parse()
extractor.return_list()
It will print out:
[[1, 2], [3, 4]]

"""
soup = BeautifulSoup(table_doc, 'html.parser')
extractor = Extractor(soup, id_='wanted')
extractor.parse()
extractor.return_list()
It will print out:
[[u'1', u'2'], [u'3', u'4']]
Example 4 - Complex
| 1 | 2 | 3 |
| 4 | ||
| 5 | ||
from html_table_extractor.extractor import Extractor
table_doc = """

<tr>
<td rowspan=2>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td colspan=2>4</td>
</tr>
<tr>
<td colspan=3>5</td>
</tr>
</table>
"""
extractor = Extractor(table_doc)
extractor.parse()
extractor.return_list()
It will print out:
[[u'1', u'2', u'3'], [u'1', u'4', u'4'], [u'5', u'5', u'5']]
Example 5 - Conflicted
| 1 | 2 | 3 |
| 4 | ||

<td>2</td>
<td rowspan=3>3</td>
</tr>
<tr>
<td colspan=2>4</td>
</tr>
<tr>
<td colspan=2>5</td>
</tr>
</table>
"""
extractor = Extractor(table_doc)
extractor.parse()
extractor.return_list()
It will print out:
[[u'1', u'2', u'3'], [u'1', u'4', u'3'], [u'5', u'5', u'3']]
Example 6 - Write to file
| 1 | 2 |
| 3 | 4 |
from html_table_extractor.extractor import Extractor
table_doc = """
<table><tr><td>1</td><td>2</td></tr><tr><td>3</td><td>4</td></tr></table>
