要将第一行按钮规则改成每次点击开始后每0.1秒执行，可以修改clickButton方法中的setTimeout函数，将延迟时间设为0.1秒，并将console.log语句移入setTimeout函数中。具体修改如下：

clickButton (index, delay) {
  this.items[index].active = true
  setTimeout(() => {
    console.log(`Clicked button ${index + 1}`)
    this.items[index].active = false
  }, 100)

  if (this.items[2].checked) {
    setTimeout(() => {
      console.log('Clicked button 1 of the third row')
    }, delay)
    setTimeout(() => {
      console.log('Clicked button 3 of the third row')
    }, delay + 300)
  }

  if (index === 0) {
    setTimeout(() => {
      this.clickButton(index, delay)
    }, 100)
  }
}

这样修改后，当点击第一行按钮时，会在开始后立即执行一次clickButton方法，并且每0.1秒执行一次，直到该按钮被停止或取消勾选。
