el-table 用formatter 将接口返回的 多个数字类型的字符串 转换成对应汉字

formatter ：用来格式化内容

<el-table-column label="支付方式" width="180" prop="payTypes" :formatter="formatType" show-overflow-tooltip header-align="center" align="center"></el-table-column> 

后台返回的数据结构是这样的

 list:[
	  {
      id:'MK00000001',  payTypes:'1,3'},                
      {
      id:'MK00000002',  payTypes:'1,2,3,4,5'},
	  {
      id:'MK00000003',  payTypes:'1,2,3,4,5'}
 ]

将payTypes的属性值根据逗号截取

   formatType(row, column) {
    
	let payTypeList = row.payTypes.split(",")
        for (var i = 0; i < payTypeList.length; i++) {
    
          switch (payTypeList.length - i) {
    
            case 1: {
    
              payTypeList[i] = '现金 '
              break;
            }
            case 2: {
    
              payTypeList[i] = '微信 '
              break;
            }
            case 3: {
    
              payTypeList[i] = '支付宝 '
              break;
            }
            case 4: {
    
              payTypeList[i] = '银联 '
              break;
            }
            case 5: {
    
              payTypeList[i] = '其他 '
              break;
            }
          }
        }
        return payTypeList
      },
