可以使用Vue和Element UI的表格组件来提取vehicleModelAmountData的vehicleModelName属性的值和freightRate的值，组成表格的属性和值。具体步骤如下：

1. 将vehicleModelAmountData的值从字符串转换为数组，使用JSON.parse()方法来实现：

let vehicleModelAmountData = JSON.parse(data.vehicleModelAmountData);

2. 定义表格的列属性，包括vehicleModelName和freightRate：

const columns = [
  {
    label: '车型名称',
    prop: 'vehicleModelName'
  },
  {
    label: '运费',
    prop: 'freightRate'
  }
];

3. 遍历vehicleModelAmountData数组，将每个对象的vehicleModelName和freightRate属性的值存储到一个新的数组中：

const tableData = vehicleModelAmountData.map(item => ({
  vehicleModelName: item.vehicleModelName,
  freightRate: item.freightRate
}));

4. 在Vue模板中使用Element UI的表格组件，将columns和tableData传递给表格组件的props：

<template>
  <el-table :data="tableData" :columns="columns"></el-table>
</template>

<script>
export default {
  data() {
    return {
      columns: [
        {
          label: '车型名称',
          prop: 'vehicleModelName'
        },
        {
          label: '运费',
          prop: 'freightRate'
        }
      ],
      tableData: []
    };
  },
  mounted() {
    let vehicleModelAmountData = JSON.parse(data.vehicleModelAmountData);
    this.tableData = vehicleModelAmountData.map(item => ({
      vehicleModelName: item.vehicleModelName,
      freightRate: item.freightRate
    }));
  }
};
</script>

这样就可以在页面上展示一个包含vehicleModelName和freightRate两列的表格了。
