在 jupyter notebook 中显示 pandas dataframe 字体较大

Question

I have a small-shaped (5 rows, 3 columns) dataframe which I can display by calling df in jupyter cell. I would like to enlarge (font size) this output for presentation purpose. Is it possible?

Answer 1

You can play around with styles using df.style.set_table_styles()

This might help:

heading_properties = [('font-size', '18px')]

cell_properties = [('font-size', '16px')]

dfstyle = [dict(selector="th", props=heading_properties),\
 dict(selector="td", props=cell_properties)]

df.style.set_table_styles(dfstyle)

Answer 2

You can simply use this code in one line:

df.style.set_table_attributes('style="font-size: 17px"')

Answer 3

In order to change the default HTML style for all dataframes in a notebook and not having to apply the style individually to each dataframe, you have two options:

1. For a single notebook use the magic function %%html :

   In the first cell of your notebook put

   %%html <style> /* Any CSS style can go in here. */.dataframe th { font-size: 18px; }.dataframe td { font-size: 16px; } </style>

2. For all notebooks adjust the Jupyter CSS style:

   Add the CSS style information

   .dataframe th { font-size: 18px; }.dataframe td { font-size: 16px; }

   to one of the following files:

   • Jupyter Notebook :

     $HOME/.jupyter/custom/custom.css

   • JupyterLab (depending on the theme):

     $HOME/anaconda3/envs/[ENVIRONMENT NAME]/share/jupyter/lab/themes/@jupyterlab/theme-dark-extension/index.css

     or

     $HOME/anaconda3/envs/[ENVIRONMENT NAME]/share/jupyter/lab/themes/@jupyterlab/theme-light-extension/index.css

     For the JupyterLab the custom.css is unfortunateley not used, so I do not see another way to change the CSS.
