我使用flexbox css实现了一个简单的角度材质表。
当我在XS屏幕视图中看到表格时,表格列之间的间距未正确调整..
有没有办法可以添加水平滚动来正确地对表格列进行空间处理,方法是指定表格的最小宽度,并在XS和SM屏幕尺寸时添加水平滚动。

答案 0 :(得分:2)
要调整列之间的间距,请在mat-cell上设置min width并使用媒体查询。
例如小屏幕:
@media only screen and (max-width: 736px) and (orientation:portrait) {
mat-header-row, mat-row {
width: 200%; //you can also set it in px,em, etc...
}
}
