Answer 1

您可以在.table-responsive div

中使用airflow backfill example_bash_operator -s 2015-01-01 -e 2015-01-02

＆＃13;

＆＃13;

overflow: inherit !important;

＆＃13;

.table-responsive{overflow: inherit !important;}

＆＃13;

＆＃13;

＆＃13;

Answer 2

请使用类表而不是表响应。表响应类有一个属性overflow：hidden。

Answer 3

问题与父div的溢出有关。请参阅该div的以下代码并查看图像以供参考：

@media screen and (max-width: 767px)
tables.less:180
.table-responsive {
    width: 100%;
    margin-bottom: 15px;
    overflow-y: visible;
    -ms-overflow-style: -ms-autohiding-scrollbar;
    border: 1px solid #ddd;
    height: 120px;
}
