问题
I am trying to print a pandas DataFrame.
One of the columns is too wide (it is a very long string).
To print I am using tabulate library. But when it is printed it shows the whole content of all columns in one very long line. Here is what I see:
row name review rating
0 Planetwise Flannel Wipes These flannel wipes are OK, but in my opinion not worth keeping. I also ordered someImse Vimse Cloth Wipes-Ocean Blue-12 countwhich are larger, had a nicer, softer texture and just seemed higher quality. I use cloth wipes for hands and faces and have been usingThirsties 6 Pack Fab Wipes, Boyfor about 8 months now and need to replace them because they are starting to get rough and have had stink issues for a while that stripping no longer handles. 3
1 Planetwise Wipe Pouch it came early and was not disappointed. i love planet wise bags and now my wipe holder. it keps my osocozy wipes moist and does not leak. highly recommend it. 5
2 Annas Dream Full Quilt with 2 Shams Very soft and comfortable and warmer than it looks...fit the full size bed perfectly...would recommend to anyone looking for this type of quilt 5
3 Stop Pacifier Sucking without tears with Thumbuddy To Love\'s Binky Fairy Puppet and Adorable Book This is a product well worth the purchase. I have not found anything else like this, and it is a positive, ingenious approach to losing the binky. What I love most about this product is how much ownership my daughter has in getting rid of the binky. She is so proud of herself, and loves her little fairy. I love the artwork, the chart in the back, and the clever approach of this tool. 5

as you can see the line is too long. How can I limit the number of characters in the printed string? For example I would like that line 3 to be printed as something like this:
3 Stop Pacifier Sucking without tears ... This is a product well worth ... 5
I want this limitation to be applied to all lines in the table.

There's max_colwidth and (terminal) width:
In [11]: pd.options.display.width = 50
In [12]: pd.options.display.max_colwidth = 50
In [13]: df
Out[13]:

You can do something like this:
df['column_name'] = df['column_name'].str[:width]

try this one:
pd.options.display.width = 1200
pd.options.display.max_colwidth = 100
pd.options.display.max_columns = 100
