在工作中通常会遇到Table表格匹配字典项中的数据这里介绍几种方法大家仅供参考

    <el-table
      :data="tableData"
      style="width: 100%">
      <el-table-column prop="date" label="日期" width="180">
      </el-table-column>
      <el-table-column prop="type" label="类型" width="180">
      <template slot-scope="scope">  
      {{getChangeType(scope.row.type)}}
      </template>
      </el-table-column>
      <el-table-column prop="address" label=""
      :formatter="typeFormatter">
      </el-table-column>
      <el-table-column prop="address" label="地址">
      </el-table-column>
    </el-table>

data() {
        return {
        list: [{
          value: '1',
          label: '张三'
        }, {
          value: '2',
          label: '李四'
        }, {
          value: '3',
          label: '李二'
        }],
        }
      },
methods: {
	//1.使用插槽（个人推荐）
	getChangeType(e) {
      for (var i = 0; i < this.List.length; i++) {
        if (this.List[i].value == e) {
          return this.List[i].label;
        }
      }
    },
   //2.使用:formatter
   typeFormatter: function(row, column) {
        return row.type == 1
          ? "张三"
          : row.type == 2
            ? "李四"
            : row.type == 3 ? "李二" : "你猜？";
		}
	}
	//当然也可以用switch
	typeFormatter: function(row, column) {
      switch (row.type) {
        case "1":
          return "张三";
          break;
        case "2":
          return "李四";
          break;
        case "3":
          return "李二";
          break;
      }
}
