element ui里面table分页,页数从0开始的怎么做？

需求:
后台请求的接口是从0页开始的,但是pagination是从1开始的,就是在点击pagination的第1页是后台转0
1首先在data里面定义为1,其他地方也是定义1

 return {
      formSearch: {
        name: '',
        phone: '',
        page: 1,
        size: 10
      }
}

2.在接口这里去重新创建一个对象,进行浅拷贝

 getSalesList () {
      this.loading = true
      setTimeout(() => {
        this.loading = false
      }, 20000)
      let data = Object.assign({}, this.formSearch, {
        page: this.formSearch.page - 1
      })
      Fetch.saleslist(data).then(res => {
        this.loading = false
        if (res.status === 200) {
          let data = res.data.data
          this.list = data.content
          this.totalElementsData = +data.totalElements
        } else {
          this.$message({
            message: res.data.message,
            duration: 3000
          })
        }
      })
    },

也就是这个
let data = Object.assign({}, this.formSearch, {
page: this.formSearch.page - 1
})
嗯嗯嗯嗯 就是这样
