如何通过`DataTable`定义将CSS应用于<table>元素(使其宽度为100%)?

问题

我正在使用new "v1.0"Dash套件(请参阅下面的点子要求)。我想创建一个DataTable,它需要全角(就像一个<p>元素一样)。

我的表格设置如下(完整的MWE):

dash_table.DataTable(
    …
    style_table={
        'maxHeight': '50ex',
        'overflowY': 'scroll',
        'width': '100%',
        'minWidth': '100%',
    },
    …

但是,即使<div class="cell cell-1-1 dash-fixed-content">生成的HTML容器是全角的,它所包含的<table>也没有,如下面的演示所示。

问题是… 相同的类似代码可用于Dash 0.x

问题

  

使用Dash 1.0,   如何使单元格自动水平扩展,以使表格填满整个水平空间?

或者换句话说,如何通过<table>元素设置DataTable元素的样式?

1 个答案:

答案 0 :(得分:1)

您可以在类中添加一个简单的单词,以为您的应用程序提供全角表格。

对此:

<div class="cell cell-1-1 dash-fixed-content">

添加此内容:

<div class="table table-bordered table-hover table-responsive cell cell-1-1 dash-fixed-content">

这将为您提供100%的总宽度,并且自然响应。怎么样?尝试调整浏览器的大小并查看效果。

希望这会有所帮助。
