element 前端排序 与 后端排序

前端排序 ：

       <el-table-column
                  prop="total_fee"
                  sortable :sort-orders="['descending','ascending']"
                  align="center"
                  label="收入情况">
                </el-table-column>

后端排序;

1.表格行

                  :sortable="'custom'"
                  align="center"
                  label="转账汇款">
                </el-table-column>

2.表格 

 <el-table
                key="3"
                align="center"

                class="table1"
                stripe
                show-summary
                :summary-method="getSummaries"
                @sort-change="changeTableSort1"
                :header-cell-style="headerCellStyle"
                :data="tableData">

3.方法

data  数据 

        // 排序 1: 总金额 2:支付宝 3:微信 4:贝宝 5:转账 6: 退款 7: 定金 8 :尾款
        incomeSort:  {
          "total": 1,
          "ali": 2,
          "wx": 3,
          "paypal": 4,
          "transfer": 5,
          "refund": 6,
          "depositFee": 7,
          "finalPayFee": 8,
        },

  changeTableSort1 (column) {
        this.orderField = column.order === 'ascending' ? -this.incomeSort[column.prop] : (column.order === 'descending' ? this.incomeSort[column.prop] : '')
        if (this.orderField) {
          this.getListHand()
        }
      },

this.getListHand() 是后端接口
