	<el-table
        ref="table"
        :data="tableData.list"
        style="width: 100%"
        :header-cell-style="{ background: 'var(--shallow-green)' }"
        :row-class-name="rowBgClass"
        border
        size="medium"
        show-summary
        :span-method="handler"
        :summary-method="getSum"
      >
        <el-table-column type="selection" width="70" align="center" />
        <el-table-column type="index" label="序号" width="70" align="center" />
        <el-table-column
          label="分包单位"
          width="200"
          align="center"
          prop="FENBAODANWEI"
        >
          <template slot-scope="scope">
            <el-button type="text" @click="checkDeatil(scope.row)">{{
              scope.row.FENBAODANWEI
            }}</el-button>
          </template>
        </el-table-column>
        <el-table-column
          v-for="(item, index) of tableData.table"
          :key="index"
          :label="item.NAME"
          align="center"
          :prop="item.ID"
        >
          <template slot-scope="scope">
            <div>
              <span>{{
                scope.row["A_" + item.ID] ? scope.row["A_" + item.ID] : 0
              }}</span>
            </div>
          </template>
        </el-table-column>
      </el-table>

主要是需要ref以及show-summary， :span-method=“handler” 和 :summary-method=“getSum”

method

handler() {
      this.$nextTick((x) => {
        if (this.$refs.table.$el) {
          var current = this.$refs.table.$el
            .querySelector(".el-table__footer-wrapper")
            .querySelector(".el-table__footer");
          var tds = current.rows[0].cells;
          tds[0].style.display = "none";
          tds[1].style.display = "none";
          tds[2].colSpan = "3";
        }
      });
    },
    getSum(param) {
        if (this.countArr) {
          const { columns, data } = param;
          const sums = [];
          columns.forEach((column, index) => {
            console.log(column, index, "aaaaaaaa", this.countArr);
            if (column.property != undefined && index === 2) {
              sums[index] = "合计";
              return;
            }else if(column.property != undefined && index === 3){
              sums[index] = this.countArr[0].A_111V6320230B
            }else if(column.property != undefined && index === 4){
              sums[index] = this.countArr[0].A_1J2B27A12328
            }
          });

          return sums;
        }
    },
