在component.html中

<md-table [dataSource]="dataSource">
    <ng-container mdColumnDef="a">
      <md-header-cell *mdHeaderCellDef> a </md-header-cell>
      <md-cell *mdCellDef="let element"><a routerLink="{{element.number}}"> {{element.a}} </a></md-cell>
    </ng-container>

    <ng-container mdColumnDef="b">
      <md-header-cell *mdHeaderCellDef> b </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.b}} </md-cell>
    </ng-container>

    <md-header-row *mdHeaderRowDef="['a','b']"></md-header-row>
    <md-row *mdRowDef="let row; columns: ['a','b']" (click)="selectRow(row)"></md-row>
  </md-table>

并在component.ts

selectRow(row) {
   console.log(row);
 }
