vue+el-table實現合並單元格

本文實例為大傢分享瞭el-table實現合並單元格的具體代碼,供大傢參考,具體內容如下

el-table合並單元格(vue+element)

– 先在el-table放入:span-method=”arraySpanMethod”

<el-table :header-cell-style="{background:'#eef1f6',color:'#606266'}" :data="merchantList" border :span-method="arraySpanMethod">
          <el-table-column align="center" prop="provinceName" label="省份"> </el-table-column>
          <el-table-column align="center" label="代理商名稱">
            <template scope="scope">
              <span>{{scope.row.parentMerchantName == scope.row.merchantName ? '---' : scope.row.parentMerchantName}}</span>
            </template>
          </el-table-column>
          <el-table-column align="center" prop="cityName" label="市"> </el-table-column>
          <el-table-column align="center" prop="countryName" label="區"> </el-table-column>
          <el-table-column align="center" prop="merchantName" label="門店"> </el-table-column>
</el-table>

在methods中寫入方法:

//合並單元格
arraySpanMethod ({ row, column, rowIndex, columnIndex }) {
      if (columnIndex === 0) {//第一列的合並方法,省
        const _row_1 = this.provinceArr[rowIndex];
        const _col_1 = _row_1 > 0 ? 1 : 0; //如果被合並瞭_row=0則它這個列需要取消
        return {
          rowspan: _row_1,
          colspan: _col_1
        }
      } 
    },
    //初始化
    merageInit () {
      this.provinceArr = []
      this.provincePos = 0
    },
    //要合並的數組的方法
    merage () {
      this.merageInit()
      for (var i = 0; i < this.merchantList.length; i++) {
        if (i === 0) {
          //第一行必須存在
          this.provinceArr.push(1)
          this.provincePos = 0
        } else {
          // 判斷當前元素與上一個元素是否相同 this.provincePos是provinceArr內容的序號
          //省
          if (this.merchantList[i].provinceName === this.merchantList[i - 1].provinceName) {
            this.provinceArr[this.provincePos] += 1
            this.provinceArr.push(0)
          } else {
            this.provinceArr.push(1)
            this.provincePos = i
          }
        }
      }
    },
