点击确认后，怎么把这一列的确认改为确认成功

<el-table-column fixed="right" label="操作" width="200" align="center">
                <template slot-scope="scope">
                    <el-button @click="open(scope.row)" type="button" class="confirmbtn">{{sure}}</el-button>
                    <el-button @click="handleClick(scope.row)" type="button" class="seebtn">详细</el-button>
                </template>
            </el-table-column>

async open(e) {
                console.log(e,'id');
                this.getinfo.finance_id = this.rowdata.id || e.id
                const res = await this.$http.post("/finance/agree", this.getinfo)
                console.log(res, 'process');
                this.$message({
                    message: "您已成功确认",
                    type: "success",
                });
                // this.sure='1'
            },

open再传个索引过去,变量sure放到列表去

<el-button @click="open(scope.row,scope.$index)" type="button" class="confirmbtn">{{scope.row.sure}}</el-button>
async open(e,index) {
                console.log(e,'id');
                this.getinfo.finance_id = this.rowdata.id || e.id
                const res = await this.$http.post("/finance/agree", this.getinfo)
                console.log(res, 'process');
                this.$message({
                    message: "您已成功确认",
                    type: "success",
                });
              this.tableList[index].sure='确认成功' // tableList是表格列表数组
                // this.sure='1'
            },

你点击确认成功之后，接口成功后台已经把这个状态更改了；你只需要在确认成功的接口那里再调用一下查询接口就可以了呢
