与上面几乎相同的解决方案，但如果您尝试从单击的行中获取对象，则更有用

almost the same solution as above but a bit more useful if you are trying to get the object from the clicked row

<mat-row  *matRowDef="let row; columns: displayedColumns;" (click)="getRecord(row)"></mat-row>

当您控制台记录该行时，您将获得该行的整个对象

when you console log the row you will get the entire object of the row
