如何使用角度材料flexlayout避免水平和垂直滚动角度

时间：2018-04-19 14:33:00

标签： angular angular-material angular-flex-layout

我使用角度材料和柔性布局使用角度2。我已经实施了 mat-sidenav 并采用了一些 mat-form-field 并实现了 mat-table

我只为 mat-table 组件指定了max-height，但我得到了除 mat-table <的垂直滚动条之外的页面的水平和垂直滚动条/ strong>

下面显示的是我的页面。

当它进入xs视口时，我会得到多个滚动，如下所示

有人可以帮我解决如何避免这些滚动条......？

请访问我的示例代码here

你只需要调整mat-row，mat-h​​eader-row的字体和宽度，这样它们就可以放在小屏幕上，滚动条就会消失：

@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;  
   }
