I know that I've seen some example somewhere before but for the life of me I cannot find it when googling around.

I have some rows of data:

data = [[1,2,3],
        [4,5,6],
        [7,8,9],
        ]

And I want to output this data in a table, e.g.

+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
| 7 | 8 | 9 |
+---+---+---+

Obviously I could use a library like prettytable or download pandas or something but I'm very disinterested in doing that.

I just want to output my rows as tables in my Jupyter notebook cell. How do I do this?

I finally re-found the jupyter/IPython documentation that I was looking for.

I needed this:

from IPython.display import HTML, display

data = [[1,2,3],
        [4,5,6],
        [7,8,9],
        ]

display(HTML(
   '<table><tr>{}</tr></table>'.format(
       '</tr><tr>'.join(
           '<td>{}</td>'.format('</td><td>'.join(str(_) for _ in row)) for row in data)
       )
))

(I may have slightly mucked up the comprehensions, but display(HTML('some html here')) is what we needed)
