SAP Spartacus B2B ListComponent响应回车事件的实现

SAP Spartacus B2B的List页面：

和回车键事件相关的实现：

<cx-table
        *ngIf="data.values?.length > 0; else emptyList"
        [structure]="structure"
        [data]="data.values"
        [i18nRoot]="domainType"
        [currentItem]="{ property: key, value: currentKey$ | async }"
        (launch)="launchItem($event)"
        [cxFocus]="{ trap: 'both' }"
      >
      </cx-table>

调用栈：观察lock-focus.directive.ts里的handleEnter函数是如何被Angular core调用的：

传入focus directive的事件：KeyboardEvent

• code为Enter
• currentTarget: cx-table.vertical
• eventPhase: 3
• key: Enter
• keyCode: 13

类型：keydown
