如何在FullCalendar ResourceTimeline中显示两天之间的间隔？

document.addEventListener('DOMContentLoaded', function() {
  var calendarEl = document.getElementById('calendar');

  var calendar = new FullCalendar.Calendar(calendarEl, {
    plugins: ['resourceTimeline'],
    defaultView: 'resourceTimelineDay',
    slotDuration: '00:15:00', // 设置每个时间槽的持续时间为15分钟
    slotLabelInterval: '01:00:00', // 设置时间槽标签的显示间隔为1小时
    resources: [
      { id: 'a', title: 'Resource A' },
      { id: 'b', title: 'Resource B' }
    ],
    events: [
      { id: '1', resourceId: 'a', start: '2022-01-01T08:00:00', end: '2022-01-01T12:00:00' },
      { id: '2', resourceId: 'b', start: '2022-01-01T09:00:00', end: '2022-01-01T11:00:00' },
      { id: '3', resourceId: 'a', start: '2022-01-02T10:00:00', end: '2022-01-02T14:00:00' },
      { id: '4', resourceId: 'b', start: '2022-01-02T11:00:00', end: '2022-01-02T13:00:00' }
    ]
  });

  calendar.render();
});
