vue element-ui中table合計指定列求和例項

阿新 • • 發佈：2020-11-04

注意點：

1. <el-table> 中加:summary-method="getSummaries"

2. <el-table-column> 中要加 prop

// 房間號的合計去掉
 getSummaries (param) {
  const { columns,data } = param
  const sums = []
  columns.forEach((column,index) => {
  if (index === 0) {
   sums[index] = '總計'
  } 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
 }

補充知識：vue+elementUI的表格最後一行合計自定義顯示

1.在看了elementUI的文件後重要的倆個屬性是 show-summary :summary-method="getSummaries" getSummaries這個是自定義方法函式的方法。

HTML的程式碼：

show-summary :summary-method="getSummaries的屬性要加上，還有一個很重要的一點就是要必須要在el-table-column中必須是prop來傳值"

<el-table :key='tableKey' :data="listData" show-summary :summary-method="getSummaries" v-loading="listLoading" border fit highlight-current-row
    style="width:100%;margin-top:8px" :header-cell-style="{background:'oldlace'}">>
    
     <el-table-column prop="equipmentType" align="center" label="裝置型別" min-width="50">
     </el-table-column>
     <el-table-column prop="equipmentName" align="center" label="裝置名稱" min-width="50">
     </el-table-column>
     <el-table-column prop="equipmentCode" align="center" label="裝置編號" min-width="50">
     </el-table-column>
     <el-table-column prop="openRate" align="center" label="開機率" min-width="50">
     </el-table-column>
     <el-table-column prop="planWorkTime" align="center" label="計劃工作時間" min-width="50">
     </el-table-column>
     <el-table-column prop="closeTime" align="center" label="關機時間(h)" min-width="50">
     </el-table-column>
     <el-table-column prop="machiningTime" align="center" label="加工時間(h)" min-width="50">
     </el-table-column>
     <el-table-column prop="stopTime" align="center" label="停工時間(h)" min-width="50">
     </el-table-column>
     <el-table-column prop="debugTime" align="center" label="除錯時間(h)" min-width="50">
     </el-table-column>
 
    <el-table-column align="center" label="檢視" min-width="210">
     <template slot-scope="scope">
     <el-button title="時序圖" type="primary" size="mini" @click="profile(scope.row)" v-show="SXTbatshow">時序圖</el-button>
     <el-button title="狀態時長統計圖" type="danger" size="mini" @click="cartogram(scope.row)">狀態時長統計圖</el-button>
     <el-button title="狀態佔比圖" type="success" size="mini" @click="diagram(scope.row)">狀態佔比圖</el-button>
     </template>
    </el-table-column>
    </el-table>

在script要寫的程式碼：

// 表格總計的時間
 getSummaries(param) {
  const { columns,data } = param;
  /* console.log(1234)
  console.log(param) */ 
  const sums = [];
  columns.forEach((column,index) => {
   if (index === 0) {
   sums[index] = '總計';
   return;
   }
   //this.closeList等等是後臺返回的總的資料，然後取值到這裡
   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;
  },
