angular - 如何使用 Angular Material 柔性布局避免 Angular 水平和垂直滚动

我正在使用 Angular Material 和弹性布局来处理 Angular 2。我已经实现了 ma​​t-sidenav 并采用了一些 ma​​t-form-field 并且还实现了 ma​​t-table

我只为 ma​​t-table 组件指定了最大高度,但是除了 ma​​t-table< 的垂直滚动条之外,我还得到了页面的水平和垂直滚动条/strong>

下图是我的页面。

enter image description here

当进入 xs 视口(viewport)时,我得到多个滚动条,如下所示

enter image description here

谁能帮我解决如何避免这些滚动条......?

请访问我的示例代码here

最佳答案

你只需要调整mat-row,mat-h​​eader-row的字体和宽度,这样它们就可以适应小屏幕并且滚动条会消失:

@media only screen and (max-width: 736px) and (orientation:portrait) {
mat-header-row, mat-row {
width: 100%;
}

mat-row{
font-size:8px;
}

mat-cell{
font-size:8px;
}
