Question

我在此处添加了我的plunker链接https://plnkr.co/edit/TD6iQJvIExwTeJ9QPbRS?p=preview

我希望提交按钮显示在表格的右下方。我的表格宽度根据数据而变化。我桌子的宽度是自动的。那么我每次如何将按钮置于右下角。

您可以尝试使用此代码。

尝试从tbody中删除最后一个tr并检查宽度和按钮位置。

将Grid类更改为col-sm-12，并将表的宽度设置为100％。添加了预览， https://plnkr.co/edit/M3p2bpj460niGCu59irR?p=preview

当宽度为自动时，如何将按钮定位到桌子的底部？
