Question

您好，我按照粘性标头行https://material.angular.io/components/table/overview#sticky-rows-and-columns的角度材料文档示例但不要为我工作这是我的html代码

<div class="content mat-white-bg">
    <mat-table #table [dataSource]="dataSource"
       matSort matSortDirection="asc" matSortDisableClear>

      <ng-container matColumnDef="Code">
        <mat-header-cell *matHeaderCellDef mat-sort-header>
          <mat-form-field>
            <input matInput (keyup)="applyFilter($event.target.value)" placeholder="{{'Kodi' | translate}}">
          </mat-form-field>
          <button (click)="sortTable($event.target.value)" mat-button class="mat-icon-button ">
            <mat-icon>sort</mat-icon>
          </button>
        </mat-header-cell>
        <mat-cell *matCellDef="let client">
          <p class="text-truncate ">
            {{client.Code}}
          </p>
        </mat-cell>
      </ng-container>

      <ng-container matColumnDef="FirstName">

        <mat-cell *matCellDef="let client" fxHide fxShow.gt-sm>
          <p class="text-truncate ">
            {{client.Address}}
          </p>
        </mat-cell>
      </ng-container>

      <ng-container matColumnDef="City">
        <mat-header-cell *matHeaderCellDef mat-sort-header fxHide fxShow.gt-sm>
          <mat-form-field>
            <input matInput (keyup)="applyFilter($event.target.value)" placeholder="{{'Qyteti' | translate}}">
          </mat-form-field>
          <button (click)="sortTable()" mat-button class="mat-icon-button ">

        </mat-cell>
      </ng-container>


      <ng-container matColumnDef="Email">
        <mat-header-cell *matHeaderCellDef mat-sort-header fxHide fxShow.gt-sm>
          <mat-form-field>
            <input matInput (keyup)="applyFilter($event.target.value)" placeholder="Email">
          </mat-form-field>

        <mat-cell *matCellDef="let client" fxHide fxShow.gt-sm>
          <p class="email text-truncate">
            {{client.Email}}
          </p>
        </mat-cell>
      </ng-container>

      <ng-container matColumnDef="Tel">
        <mat-header-cell *matHeaderCellDef mat-sort-header fxHide fxShow.gt-sm>
          <mat-form-field>
            <input matInput (keyup)="applyFilter($event.target.value)" placeholder="Tel">
          </mat-form-field>
          <button (click)="sortTable()" mat-button class="mat-icon-button ">
            <mat-icon>sort</mat-icon>
          </button>
        </mat-header-cell>
        <mat-cell *matCellDef="let client" fxHide fxShow.gt-sm>

          {{client.Tel}}

        </mat-cell>
      </ng-container>
      <mat-header-row *matHeaderRowDef="displayedColumns; sticky: true"></mat-header-row>
      <mat-row *matRowDef="let client; columns: displayedColumns;"
               class="client"></mat-row>
    </mat-table>
</div>

我已将sticky设置为true（如示例），但出现错误无法绑定到“ matHeaderRowDefSticky”，因为它不是“ mat-header-row”的已知属性

Answer 1

sticky属性在6.3.0版本中引入。您可以升级@angular/material和@angular/cdk来解决问题

选中此Github issue

Answer 2

如果您无法将@angular/material升级到新版本，这是一个简单的css实现，我已经使用它来获取@angular/material版本5.1.0中的粘性标头行：

.mat-header-row--sticky {
  position: sticky;
  top: 0;
  background: inherit;
  z-index: 100;
}

然后在模板中将类mat-header-row--sticky添加到mat-header-row元素：

<mat-header-row *matHeaderRowDef="displayedColumns" class="mat-header-row--sticky"></mat-header-row>

角材料粘性行不起作用
