如何从AgEditorComponent上下文聚焦ag角度中的下一个单元格

import { Component } from '@angular/core';

@Component({
  selector: 'app-ag-editor',
  template: `
    <input [(ngModel)]="value" (keydown)="onKeyDown($event)">
  `,
})
export class AgEditorComponent {
  private params: any;
  public value: any;

  agInit(params: any): void {
    this.params = params;
    this.value = params.value;
  }

  getValue(): any {
    return this.value;
  }

  isPopup(): boolean {
    return true;
  }

  onKeyDown(event: KeyboardEvent): void {
    if (event.key === 'Enter' || event.key === 'Tab') {
      event.preventDefault();

      const editingCells = this.params.api.getEditingCells();
      const currentCell = editingCells[0];
      const currentRowIndex = currentCell.rowIndex;
      const currentColumn = currentCell.column;

      let nextRowIndex = currentRowIndex;
      let nextColumn = currentColumn;

      // 计算下一个单元格的位置
      if (event.key === 'Enter') {
        nextRowIndex++;
      } else if (event.key === 'Tab') {
        const columns = this.params.columnApi.getAllDisplayedColumns();
        const currentColumnIndex = columns.indexOf(currentColumn);
        nextColumn = columns[currentColumnIndex + 1];
        if (!nextColumn) {
          nextColumn = columns[0];
          nextRowIndex++;
        }
      }

      // 聚焦到下一个单元格并开始编辑
      this.params.api.startEditingCell({
        rowIndex: nextRowIndex,
        colKey: nextColumn.getColId(),
      });
    }
  }
}
