合并

 表格el-table添加方法:span-method="”

 <el-table v-loading="listLoading" :data="SHlist" ref="tableList" element-loading-text="Loading" border fit   highlight-current-row :header-cell-style="headClass" style="margin-top:15px" :span-method="objectSpanMethod">

 下面是我需求，合并第二列，第五

 //合并单元格objectSpanMethod({row,column,rowIndex,columnIndex,index2}) {if (columnIndex === 4) { //下标是4的那一列const _row = this.spanArr[rowIndex];const _col = _row > 0 ? 1 : 0;console.log(_col, '_col');return {rowspan: _row, //行colspan: _col //列};}if (columnIndex === 1) {const _row = this.spanArr[rowIndex];const _col = _row > 0 ? 1 : 0;console.log(_col, '_col');return {rowspan: _row, //行colspan: _col //列};}},

添加方法 

    getSpanArr(data) {this.spanArr = [];for (var i = 0; i < data.length; i++) {if (i === 0) {this.spanArr.push(1);this.pos = 0;} else {// 判断当前元素与上一个元素是否相同if (data[i].originalOrder === data[i - 1].originalOrder && data[i].originalOrder) {this.spanArr[this.pos] += 1;this.spanArr.push(0);} else {this.spanArr.push(1);this.pos = i;}}}console.log(this.spanArr, ' this.spanArr');},getSpanArr2(data) {this.spanArr = [];for (var i = 0; i < data.length; i++) {if (i === 0) {this.spanArr.push(1);this.pos = 0;} else {// 判断当前元素与上一个元素是否相同if (data[i].storeName === data[i - 1].storeName && data[i].storeName) {this.spanArr[this.pos] += 1;this.spanArr.push(0);} else {this.spanArr.push(1);this.pos = i;}}}},

下面是使用，获取倒接口数据后进行数据整合

  this.getSpanArr(this.SHlist);this.getSpanArr2(this.SHlist);
