如何在角形物料表中连续显示表标题? [英] How to display the table headers in a row, in angular material table?

问题描述

我的材料"表以以下方式显示值:

姓名|数量

芒果| 10

    <div class="table-cover center-table">
      <div class="mat-elevation-z8 elevation-scroll-control">
        <table mat-table class="full-width-table left-margin" [dataSource]="dataSource" matSort aria-label="Elements">

          <!-- Name Column -->
          <ng-container matColumnDef="name">
            <td mat-header-cell *matHeaderCellDef >Name</td>
            <td mat-cell *matCellDef="let row" class="">
              <div class="cell-style padding-left">{{row.Name}}</div>
            </td>
          </ng-container>

          <!-- quantity Column -->
          <ng-container matColumnDef="quantity">
            <td mat-header-cell *matHeaderCellDef>quantity</td>
            <td mat-cell *matCellDef="let row">
              <div class="cell-style">{{row.quantity}}</div>
            </td>
          </ng-container>

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

      </div>      
    </div>

但是我想显示如下值:

名称 |芒果

质量 | 10

我该如何实现?任何帮助都非常感激

推荐答案

您可以通过以下方式实现:

You may do that by:

1. 将数据从列转移到行:

1. Transposing your data from columns to row:

Before: Mango |10 Banana|5

Before: Mango |10 Banana|5

After: Mango|Banana 10|5

After: Mango|Banana 10|5

包括标签作为数据的第一列:

Including the labels as the first column of your data:

Name|Mango|Banana Quantity|10|5

Name|Mango|Banana Quantity|10|5

调整表以动态显示列(以便您可以具有任意数量的列)，如本示例中的

Adjust your table to display columns dynamically (so that you may have any number of columns), as on this example from angular material table documentation:

<table mat-table [dataSource]="data" class="mat-elevation-z8">
  <ng-container [matColumnDef]="column" *ngFor="let column of displayedColumns">
    <th mat-header-cell *matHeaderCellDef> {{column}} </th>
    <td mat-cell *matCellDef="let element"> {{element[column]}} </td>
  </ng-container>

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

1. 如果不需要，您可以删除标题行

1. If not required you may remove the header row

如果要格式化第一列，则可以使用一些CSS作为:

If you want to format the first column, you may use some css as:

td.mat-cell:nth-child(1) { // formatting }

td.mat-cell:nth-child(1) { // formatting }

此外，如果需要，您可以使用MatColumnDef的属性粘滞性来保持第一列发粘(在这种情况下，您可能希望将第一列与动态* ngFor循环分开，以便您可以轻松地仅第一列为粘性)

Also, if required, you may use property sticky of MatColumnDef to keep the first column sticky (in this case you may want to have the first column separate from the dynamic *ngFor loop, so that you may easily have only the first column sticky)

我已经创建了一个有效的 stackblitz示例
