【中文标题】使用引导程序缩小列之间的间隙【英文标题】：Closing the gap between columns with bootstrap 【发布时间】：2019-03-23 00:24:39 【问题描述】：我无法缩小引导程序中表格元素之间的差距。它给了我一个奇怪的 60% 的差距，我似乎无法修复。我相信这与我正在尝试实施的网格系统有关。我尝试过内联样式，但似乎无法缩小差距。谁能建议一个快速修复？
干杯

【问题讨论】：
你为什么用桌子？ 如果你把它放在modal 中，不建议使用container，因为它会使你的模态变得难以管理
那是因为你使用了col-md-6。你不遵循引导程序的网格系统。
【参考方案1】：
我不确定您的问题，但在您的代码中看到您可以尝试：
-
使用
row 类作为每个 col-*-* 元素的父级，例如在您的情况下使用 form-group 类。
您还可以将no-gutters 添加到row 类中，以删除每个col-*-* 类的填充
添加table-sm 以尽量减少表中行的填充。
