表格内垂直滚动

Question

我正在开发一个带有垫子表的 Angular 应用程序。我想让表格可以通过粘性标题滚动。但是，滚动条似乎出现在表格之外。

我尝试使用具有高度和溢出属性的容器，但无法成功将滚动条放置在表格内。与 ngx-scrollbar 和 perfect-scrollbar 等 npm 包的结果相同。

有没有办法使用纯CSS设置表格内的滚动条？

Answer 1

使用

flexbox

涉及很多更改，我不能保证它是所有场景的最佳解决方案，但您可以使用桌子上的

display:flex

并在桌子上的

overflow-y: scroll

上设置

tbody

来实现！

CSS

/* Add application styles & imports to this file! */
@import 'node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css';

.my-table {
  overflow: hidden !important;
}
.my-table table[mat-table] {
  overflow: hidden;
  display: flex !important;
  flex-direction: column;
}
.my-table table[mat-table] {
  overflow: hidden;
  display: flex !important;
  flex-direction: column;
  height: inherit;
}
.my-table table[mat-table] thead tr {
  display: flex;
  align-items: center;
  justify-content: center;
}
.my-table table[mat-table] thead tr th {
  display: flex;
  flex: 1;
  height: 100%;
  align-items: center;
  justify-content: center;
}
.my-table table[mat-table] tbody {
  overflow-y: scroll !important;
}
.my-table table[mat-table] tbody tr {
  display: flex;
  align-items: center;
  justify-content: center;
}
.my-table table[mat-table] tbody tr td {
  display: flex;
  flex: 1;
  height: 100%;
  align-items: center;
  justify-content: center;
}

html

<div class="my-table">
  <table mat-table [dataSource]="dataSource" class="mat-elevation-z8">
    <!--- Note that these columns can be defined in any order.
      The actual rendered columns are set as a property on the row definition" -->

    <!-- Position Column -->
    <ng-container matColumnDef="position">
      <th mat-header-cell *matHeaderCellDef>No.</th>
      <td mat-cell *matCellDef="let element">{{ element.position }}</td>
    </ng-container>

    <!-- Name Column -->
    <ng-container matColumnDef="name">
      <th mat-header-cell *matHeaderCellDef>Name</th>
      <td mat-cell *matCellDef="let element">{{ element.name }}</td>
    </ng-container>

    <!-- Weight Column -->
    <ng-container matColumnDef="weight">
      <th mat-header-cell *matHeaderCellDef>Weight</th>
      <td mat-cell *matCellDef="let element">{{ element.weight }}</td>
    </ng-container>

    <!-- Symbol Column -->
    <ng-container matColumnDef="symbol">
      <th mat-header-cell *matHeaderCellDef>Symbol</th>
      <td mat-cell *matCellDef="let element">{{ element.symbol }}</td>
    </ng-container>

    <tr
      mat-header-row
      *matHeaderRowDef="displayedColumns; sticky: true"
      style="#A8ACAA"
    ></tr>
    <tr mat-row *matRowDef="let row; columns: displayedColumns"></tr>
  </table>
</div>
