为了让它与jupyter(版本4.0.6)一起工作，我创建了~/.jupyter/custom/custom.css，其中包含:

/* Make the notebook cells take almost all available width */
.container {
    width: 99% !important;
}   

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode*/
div.cell.selected {
    border-left-width: 1px !important;
}

这是我最终使用的代码。它将输入和输出单元格向左和向右拉伸。注意，输入/输出数字指示将消失:

from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))
display(HTML("<style>.output_result { max-width:100% !important; }</style>"))
display(HTML("<style>.prompt { display:none !important; }</style>"))

为了让它与jupyter(版本4.0.6)一起工作，我创建了~/.jupyter/custom/custom.css，其中包含:

/* Make the notebook cells take almost all available width */
.container {
    width: 99% !important;
}   

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode*/
div.cell.selected {
    border-left-width: 1px !important;
}

我对@jvd10的解决方案做了一些修改。“!important'似乎太强了，当TOC侧栏显示时，容器不能很好地适应。我删除了它，并添加了“min-width”来限制最小宽度。

这是我的。juyputer/custom/custom.css:

/* Make the notebook cells take almost all available width and limit minimal width to 1110px */
.container {
    width: 99%;
    min-width: 1110px;
}   

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode*/
div.cell.selected {
    border-left-width: 1px;
}

是时候使用jupyterlab了

笔记本电脑终于迎来了迫切需要的升级。默认情况下，Jupyterlab使用窗口的全宽度，就像任何其他成熟的本地IDE一样。

你所要做的就是:

pip install jupyterlab
# if you use conda
conda install -c conda-forge jupyterlab
# to run 
jupyter lab    # instead of jupyter notebook

这是来自blog.Jupyter.org的截图

如果您不想更改默认设置，并且只想更改当前正在使用的笔记本电脑的宽度，可以在单元格中输入以下内容:

from IPython.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))
