角度材料表 - 表内的顺序

Question

我正在使用Angular材质表，我想在表格中设置边框，使用CSS我可以设置边框：正常情况 [  
但是当特定细胞的内容增加时，相邻细胞的边界不会增长，并且表格看起来非常糟糕，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>

<强>方法-2： 最终，我找到了解决方案，因为材料使用我们可以使用的flex-layout CSS align-self: stretch; /* Stretch 'auto'-sized items to fit the container */ 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;
    } `

<强>方法：1 父行高度增长时，您需要拉伸表格单元格内容。 为此，您可以将表格单元格设置为弹性框，将另一个类添加到mat-cell <mat-cell class="flex-stretch">并将其添加到您的css中：

.mat-cell .flex-stretch {
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-align-self: stretch;
    -ms-flex-item-align: stretch;
    align-self: stretch;
    /* align-items center so that cell content is vertically centered */
    -webkit-align-items: center;
    -ms-flex-align: center;
    align-items: center;
}
