vue element-ui中table合计指定列求和实例

注意点：

1. <el-table> 中 加:summary-method='getSummaries'

2. <el-table-column> 中要加 prop

// 房间号的合计去掉 getSummaries (param) { const { columns, data } = param const sums = [] columns.forEach((column, index) => { if (index === 0) { sums[index] = ’总计’ } else if (index === 5 || index === 6) { const values = data.map(item => Number(item[column.property])) if (!values.every(value => isNaN(value))) { sums[index] = values.reduce((prev, curr) => { const value = Number(curr) if (!isNaN(value)) { return prev + curr } else { return prev } }, 0) } else { sums[index] = ’N/A’ } } else { sums[index] = ’--’ } }) return sums }

补充知识：vue+elementUI的表格最后一行合计自定义显示

1.在看了elementUI的文档后重要的俩个属性是 show-summary :summary-method='getSummaries' getSummaries这个是自定义方法函数的方法。

HTML的代码：

show-summary :summary-method='getSummaries的属性要加上，还有一个很重要的一点就是要 必须要在el-table-column中必须是prop来传值'

<el-table :key=’tableKey’ :data='listData' show-summary :summary-method='getSummaries' v-loading='listLoading' border fit highlight-current-row :header-cell-style='{background:’oldlace’}'>> <el-table-column prop='equipmentType' label='设备类型' min-width='50'> </el-table-column> <el-table-column prop='equipmentName' label='设备名称' min-width='50'> </el-table-column> <el-table-column prop='equipmentCode' label='设备编号' min-width='50'> </el-table-column> <el-table-column prop='openRate' label='开机率' min-width='50'> </el-table-column> <el-table-column prop='planWorkTime' label='计划工作时间' min-width='50'> </el-table-column> <el-table-column prop='closeTime' label='关机时间(h)' min-width='50'> </el-table-column> <el-table-column prop='machiningTime' label='加工时间(h)' min-width='50'> </el-table-column> <el-table-column prop='stopTime' label='停工时间(h)' min-width='50'> </el-table-column> <el-table-column prop='debugTime' label='调试时间(h)' min-width='50'> </el-table-column> <el-table-column label='查看' min-width='210'> <template slot-scope='scope'> <el-button type='primary' size='mini' @click='profile(scope.row)' v-show='SXTbatshow'>时序图</el-button> <el-button type='danger' size='mini' @click='cartogram(scope.row)'>状态时长统计图</el-button> <el-button type='success' size='mini' @click='diagram(scope.row)'>状态占比图</el-button> </template> </el-table-column> </el-table>

在script要写的代码：

// 表格总计的时间 getSummaries(param) { const { columns, data } = param; /* console.log(1234) console.log(param) */ const sums = []; columns.forEach((column, index) => { if (index === 0) { sums[index] = ’总计’; return; } //this.closeList等等是后台返回的总的数据，然后取值到这里 switch(column.property) { case 'closeTime': sums[index] = this.closeList + ’ h’ break; case 'machiningTime': sums[index] = this.machiningTimeList + ’ h’ break; case 'stopTime': sums[index] = this.stopTimeList + ’ h’ break; case 'debugTime': sums[index] = this.debugTimeList + ’ h’ break; default: break; } }); return sums; },
