如何在 vue 中使用数组数据对表格进行排序

Question

我的尝试是尝试对方法中的数据结果进行排序，但后来我想在表头中实现一个按钮，但我什至无法使用 a、b 解决方案的排序部分来自rows = [] 的数据。我可以使用 vuetify 表，但我想了解如何手动操作...

简单来说，我想按这个行数组 Amount_Raised_Millions 排序

 <template>
<div class="container-fluid">
        <div class="row mb-10">
            <main role="main" class="col-md-12 ml-sm-auto col-lg-12 pt-3 px-4">
                <div class=" pb-2 ma-3 ">
                    <h2 class="center">Funding</h2>
                    <v-divider></v-divider>
                </div>
                <div class=" table-responsive">
                <table class="table table-striped mb-0">
                    <thead>

使用computed properties 对获取的行进行排序

添加了普通表格行排序的示例（通过单击表格列名查看）

new Vue({
  el: "#app",
  data() {
    return {
      sortBy: false,
      rows: [],
    }
  },
  computed: {
    computedRows() {
      if(this.sortBy) {
        return [...this.rows]
          .sort((a, b) => a[this.sortBy] - b[this.sortBy])
      }
      return this.rows
    }
  },
  methods: {
    fillRows() {
      for(var i = 0; i < 10; i++) {
        this.rows.push({
          name: faker.name.findName(),
          date: faker.date.past(),
          amount: faker.datatype.number(),
          round: faker.datatype.number(5),
          total: faker.datatype.number(),
          founder: faker.name.findName(),
          est: faker.date.past(),
          location: faker.address.city(),
          investor: faker.name.findName(),
          employees: faker.datatype.number(50)
        })
      }
    }
  },
  mounted() {
    this.fillRows()
  },
  
  filters: {
    date(d) {
      return [
        d.getFullYear(),
        d.getMonth(),
        d.getDay()
       ].join('/')
    },
    
    year(d) { return d.getFullYear() }
  }
})
