{{}}的用法

{ {}};里面时可以直接调用方法的。

<template>
  <div>
    <el-table
      :data="tableData"
      style="width: 100%">
      <el-table-column
        prop="plateNumber"
        label="车牌号码">
      </el-table-column>
      <el-table-column
        prop="insuranceFee"
        label="保养费用">
        <template slot-scope="scope">
          <span>￥{
   
   {transFormat(scope.row.insuranceFee)}}</span>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>

<script>

  export  default {
    data(){
      return {
        tableData:[{
          plateNumber:'123456789',
          insuranceFee:'123456789'
        },
          {
            plateNumber:'123456789',
            insuranceFee:123456789
          },

          {
            plateNumber:'123456789',
            insuranceFee:123456789
          },
        ]
      }

    },
    methods:{
      transFormat(data){
        return data.toLocaleString('en-US');
      }
    }

  }

</script>
