private _evtMouseMove(event: MouseEvent) {
    const data = this._dragData;
    if (
      CellDragUtils.shouldStartDrag(
        data.pressX,
        data.pressY,
        event.clientX,
        event.clientY
      )
    ) {
      void this._startDrag(data.index, event.clientX, event.clientY);
    }
  }
