css - Angular Material 表 - 表内边框

Question

我正在使用 Angular Material 表，我想在表内设置边框，使用 CSS 我能够设置边框:正常情况[
但是，当特定单元格的内容增加时，相邻单元格的边框不会增长，表格看起来很糟糕，单元格有额外内容
这是 CSS:

`.example-container {
  display: flex;
  flex-direction: column;
  max-height: 500px;
  min-width: 300px;
}

.mat-table {
  overflow: auto;
  max-height: 500px;
}
.mat-column-name{
  border-left: 1px solid grey;
  min-height: 48px;

}
.mat-column-weight{
  border-left: 1px solid grey;

   min-height: 48px;

.mat-column-symbol{
 border-left: 1px solid grey;
   min-height: 48px;
}`

HTML`

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

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

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

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

<mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
<mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>

Answer 1

方法 2:最终，我找到了解决方案，因为 Material 使用 flex-layout 我们可以使用CSS对齐 self :拉伸(stretch)；/* 拉伸(stretch)“自动”大小的元素以适合容器 */ Result with align-self: stretch

这是更新后的 CSS

    `.example-container {
      display: flex;
      flex-direction: column;

      flex-basis: 300px;
    }

    .mat-table {
      overflow: auto;
      max-height: 500px;
    }

     .mat-column-name{
    border-right: 1px solid grey;
    align-self: stretch;
    text-align: center


    }
    .mat-column-position{
    border-right: 1px solid grey;
    align-self: stretch;
    text-align: center;

    }
    .mat-column-weight{
    border-right: 1px solid grey;
    align-self: stretch;
    text-align: center;

    } 
    .mat-column-symbol{

    text-align: center;
    align-self: stretch;
    }
   .mat-column-weight{
       align-self: stretch;
    } `
