如何隐藏移动设备上的某些列（从表中）？

标签： html css web responsive-design html-table

我在使用表时遇到很大问题 - 它们在桌面上看起来很完美 - 但在移动设备上却看不到。 所以这是我要做的事情的分手：

  • 如果@media屏幕是600px，那么列数= 3＆amp;行数= 3

  • 如果@media屏幕是460px或更少，则columnCount = 2，rowCount = 4

  • 和columnCount = 4，桌面上的rowCount = 4

我怎样才能做到这一点？

你可以在CSS技巧的移动设备上使用这个漂亮的解决方案。此解决方案使您的桌面可以在移动设备上访问，即使屏幕太窄也是如此。它不会隐藏任何列（因此它会使您的表真正响应）。

请注意您的桌子应该正常放置的桌面。在移动设备上它显然没有。你需要一些CSS技巧才能让事情发挥作用。这段代码可以实现这一点。

答案 1 :(得分：0)

将第二列隐藏在一个比600像素更窄的屏幕上的表格中，另外将第三列隐藏在比460像素更窄的屏幕上，如下所示：

@media screen and (max-width: 600px) {
    tr > *:nth-child(2) {
        display: none;
    }
}

@media screen and (max-width: 460px) {
    tr > *:nth-child(3) {
        display: none;
    }
}

根据您的喜好更改列号（2和3）。

警告：我认为这不是一个好的解决方案，因为真正的响应表会显示所有屏幕尺寸的所有内容。总的来说，我认为移动设备和桌面设备上的内容应该是相同的。仅添加此答案以满足OP的确切要求。
